<p>This layer provides the <strong>current</strong> strata parcel polygons and their associated descriptive data as a single layer to facilitate their use independently of other primary parcels or non primary parcels.</p>
<p>Strata parcels are portions of land where the vertical extent is limited.</p>
<p>The combination of this layer with the primary parcels layer provides all current parcels for New Zealand (i.e. excludes Historic and Pending parcels)</p>
<p>If you require approved or historic parcels see the <a href="http://data.linz.govt.nz/layer/1571-nz-all-parcels">All Parcels Layer</a></p>
<p>This layer has a nominal accuracy of 0.1-1m in urban areas and 1-100m in rural areas. For more detailed information about parcel accuracies please refer to the <a href="http://data.linz.govt.nz/layer/774-nz-survey-boundary-marks">Survey Boundary Marks</a> layer which contains accuracies for each parcel node.</p>
<p>The originating data for parcel/title associations includes some non-official sources where the official data does not support a link.

<p>We report on drought frequency, duration, severity, and intensity at three different time scales, short-term (3 months), medium-term (6 months) and long-term (12 months). These different time scales are approximately equivalent to meteorological, agricultural, and hydrological drought, respectively. We do this for 30 sites across Aotearoa New Zealand monitored by NIWA (National Institute for Water and Atmospheric Research) from 1972 to 2022. To measure drought events, this dataset uses the Standardised Precipitation-Evapotranspiration Index (SPEI), which incorporates temperature and precipitation. </p>
<p>Drought frequency is the number of drought events across a specified period of time. Drought duration is the number of months in a drought event. Severity is a measure of how dry a drought event is, and intensity is a measure of drought severity scaled by its duration. Extreme dryness is indicated by SPEI values of less than -2. </p>

<br /><strong>Updated with new data on 07 Dec 2023</strong><br />
<p>This dataset shows the trends of annual growing degree days (GDD) for 30 sites across New Zealand from at least 1972 to 2019. GDD are the total number of degrees Celsius above a base threshold temperature for each day. We use a base threshold of 10 degrees Celsius to report on the annual GDD for each of these sites and trends.<br>
Growing degree days (GDD) indicate the amount of warmth available for plant and insect growth and can be used to predict when flowers will bloom, and crops and insects will mature. Increased GDD means that plants and insects reach maturity faster, provided that other conditions necessary for growth are favourable, such as sufficient moisture and nutrients.</p>

<p>This indicator report trends in the number of frost days for 30 sites across Aotearoa New Zealand from 1972 to 2022. The number of frost days changes from year to year in response to variable weather patterns, and their occurrence is also influenced by climate change. Climate models project we may experience fewer cold and more warm extremes in the future. Changes in the number and timing of frost days can affect agriculture, horticulture, and viticulture, for example, by damaging and destroying crops at sensitive growth stages.</p>

<p>This indicator provides data for the number of warm days (daily maximum temperature above 25 degrees Celsius) for the 30 sites across New Zealand from at least 1972 to 2022. </p>
<p>Global average temperatures have increased by around 1 degree Celsius in the last century, almost certainly a result of high levels of atmospheric greenhouse gases emitted from human activities. While this change may seem small, relatively small changes in our climate can have big effects on our environment (Ministry for the Environment [MfE] & Stats NZ, 2019). </p>
<p>The number of warm days change from year to year in response to variable weather patterns and climate drivers. Climate models project we may experience more warm extremes in the future (IPCC, 2021). According to the WMO (2016) a decrease in cold days and nights and an increase in warm days and nights can have major implications for human health, agricultural production, and ecosystems. </p>

<br /><strong>Updated with new data on 07 Dec 2023</strong><br />
<p>This indicator measures the number of frost days for 30 sites across Aotearoa New Zealand from at least 1972 to 2022. </p>
<p>The number of frost days changes from year to year in response to variable weather patterns, and their occurrence is also influenced by climate change. Climate models project we may experience fewer cold and more warm extremes in the future. Changes in the number and timing of frost days can affect agriculture, horticulture, and viticulture, for example, by damaging and destroying crops at sensitive growth stages.</p>
<p>Variables:<br>
site: Site the NIWA climate stations represent.<br>
year: Given year the number of frost days are calculated for.<br>
Frost days: Total number of frost days are year as defined when the air temperature is below zero at 1.2m off the ground.<br>
first_frost: The first day are recorded in a given year.<br>
last_frost: The last days are recorded in a given year.<br>
lat: Approximate latitude of site location.<br>
lon: Approximate longitude of site location.<br>
site_simple: Site the NIWA climate stations represent.</p>

<br /><strong>Updated with new data on 02 Dec 2023</strong><br />
<p>This data set measures the rise in annual mean sea level relative to land referenced to the latest Intergovernmental Panel on Climate Change (IPCC) 1995 to 2014 baseline period mean sea level at four longer-term sites between 1901 and 2020:<br>
• Auckland<br>
• Wellington<br>
• Lyttelton<br>
• Dunedin<br>
and two additional sites with shorter time series:<br>
• Moturiki, Mount Maunganui (1951 to 2020)<br>
• New Plymouth (1920 to 2020).<br>
Relative sea-level rise includes the vertical land movement of the surrounding area (for example, a sinking landmass increases the relative rise in sea level).</p>
<p>We report on linear trends for sea-level rise for the full period between 1901 and 2020 for the four longer-term sites. We also publish the linear trends for these sites for two time periods: 1901 to 1960 and 1961 to 2020. For Moturiki and New Plymouth, we publish linear trends for the 1961 to 2020 period only.</p>
<p>Variables:<br>
site: The location of the tide gauge used to measure coastal sea level. Site refers to the name of nearest settlement. This dataset provides sea-level data for: (i) Auckland - Port of Auckland, Waitemata Harbour; (ii) Moturiki - Moturiki Island (Mount Maunganui); (iii) New Plymouth - Port Taranaki (New Plymouth); (iv) Wellington - Lambton Harbour (Wellington); (v) Lyttelton - Lyttelton inner harbour, and; (vi) Dunedin - Dunedin harbour basin (Otago Harbour)."<br>
trend_start_year: The first year in the annual mean sea level time series that the trend relates to.<br>
trend_end_year: The last year in the annual mean sea level time series that the trend relates to.</p>
<p>msl_trend: The estimated annual change in coastal sea level based on the trend assessment (in other words, the slope of the linear trend line). Trends were calculated using weighted linear regression models. The models used annual mean sea level data (relative the baseline) that was weighted to account for years that had less than 12 monthly average mean sea level values. Models also accounted for climatic conditions of temperature and pressure.

<p>This dataset measures the strength of extreme wind at 30 sites across Aotearoa New Zealand from 1980 to 2022. For individual sites we present the trends for the annual average of the daily maximum wind gust, and the annual maximum wind gust. </p>
<p>The annual average of the daily maximum wind gust provides information on windiness, while the annual maximum wind gust provides information on the strength of extreme wind events. </p>
<p>Variables:<br>
site: NIWA climate site.<br>
statistic: Highest max gust is maximum wind speed recorded, average max gust is monthly average calculated from highest 10min daily average, days above p99 is number of days above the 99th percentile calculated for all available daily data for each site.<br>
lat: Approx. lattitude location of NIWA climate stations to represent a site.<br>
lon: Approx. longitude location of NIWA climate stations to represent a site.<br>
p value: probability of obtaining test results at least as extreme as the result actually observed<br>
slope, conf_low, conf_high, conf_level: Sen slope statistic to describe rate of change and relevant 90% and 66% confidence intervals.<br>
z: Z score<br>

<p>This dataset measures the strength of extreme wind at 30 sites across Aotearoa New Zealand from 1980 to 2022. For individual sites, we provide data for the highest maximum wind gust, average maximum wind gust, and the number of days with wind gusts extreme for a location. The average of the daily maximum wind gust provides information on windiness, while the maximum wind gust provides information on the strength of extreme wind events. The number of days with a maximum wind gust that exceeds the 99th percentile daily maximum wind gust speed, which measures how often extreme wind events (measured as a gust that is extreme for that location) occur for a site. </p>
<p>Variables:<br>
site: NIWA climate site.<br>
statistic: Highest max gust is maximum wind speed recorded, average max gust is monthly average calculated from highest 10min daily average, days above p99 is number of days above the 99th percentile calculated for all available daily data for each site.<br>
month: Month representing data value. A month needed 100% of daily values to be calculated.<br>
year: Year representing data value.<br>
data_value: Calculated wind speed per given month and statistic.<br>
lat: Approx. latitude location of NIWA climate stations to represent a site.<br>
lon: Approx. longitude location of NIWA climate stations to represent a site.<br>
unit: Unit of data value (recorded wind speed or days above 99th percentile).</p>

<p>"Particulate matter 10 micrometres or less in diameter (PM10) in the air comprises solid particles and liquid droplets from both natural and human-made sources. PM10 can be emitted from the combustion of fuels, such as wood and coal (eg from home heating and industry), and petrol and diesel (from vehicles). Natural PM10 includes sea salt, dust, pollen, smoke (from bush fires), and volcanic ash. Nationally, burning wood or coal for home heating is the main human-made source of PM10. PM10 is of particular concern because it is found in high concentrations in some areas and can damage health. It is associated with effects ranging from respiratory irritation to some forms of cancer.</p>
<p>This dataset shows annual average PM10 concentrations for years 2006 to 2013. Field names are PM10_.<br>

<p>This data set reports on trends for 15 coastal and estuarine water quality measures, grouped below by type, monitored at sites across Aotearoa New Zealand between 2006 and 2020:</p>
<ul>
<li>nutrient – ammoniacal nitrogen, nitrate-nitrite nitrogen, total nitrogen (unfiltered), dissolved reactive phosphorus, and total phosphorus (unfiltered) </li>
<li>microbiological – faecal coliforms, <em>Enterococci</em>, and chlorophyll-<em>a</em> </li>
<li>optical – visual clarity, turbidity, and suspended solids (inorganic and organic) </li>
<li>physico-chemical – dissolved oxygen, pH, salinity, and temperature.</li>
</ul>
<p>We present trends for the period 2011 to 2020.</p>
<p>Coastal and estuarine ecosystems are affected by changes in water quality.</p>
<p><strong>Nutrients</strong><br>
The two main nutrients of concern in coastal and estuarine ecosystems are nitrogen and, to a lesser degree, phosphorus. An overload of nutrients (eutrophication) can lead to algal blooms that can kill marine life by depleting oxygen levels. Some bloom-forming algal species also contain toxins that can harm marine life, and can pass through food chains to humans (for example, via shellfish poisoning).</p>
<p><strong>Microbiological</strong><br>
Abundant <em>Enterococci _and faecal coliform bacteria indicate the possible presence of human faecal pathogens in coastal waters and represent the risk of infectious disease. Chlorophyll-_a</em> is a measure of phytoplankton biomass and is a primary indicator of eutrophication.</p>
<p><strong>Optical</strong><br>
High suspended sediment concentrations are associated with estuarine and coastal sedimentation, reduced light levels in benthic (seabed) environments, and reduced feeding rates and health of estuarine and coastal animals (Lowe et al., 2015). Visual clarity and turbidity are monitored because light affects primary production, plant and animal distributions and ecological health, aesthetic quality, and recreational values (Davies-Colley et al., 2003).</p>
<p><strong>Physico-chemical</strong><br>
Dissolved oxygen is fundamental to supporting marine life. Low levels of dissolved oxygen can have adverse effects on aquatic fauna, from reduced growth rates to death from lack of oxygen (Tomasetti & Gobler, 2020). Decreased pH results from the absorption of CO2 from the atmosphere by seawater but can also reflect local processes caused by eutrophication (Cai et al., 2011; Fraser et al., 2021). Changes in the pH of seawater can have harmful effects on marine life, impacting chemical communication, reproduction, and growth. The building of skeletons in marine organisms is particularly sensitive to acidity, so acidification (lower pH) of sea waters can be harmful for organisms such as shellfish and corals (Fabry et al., 2008). Salinity provides information on the freshwater content of coastal waters. Water temperature is important as it controls biochemical processes and affects the balance of parameters such as dissolved oxygen levels. As a result, seawater temperature determines distributions of many marine plants and animals (Kleisner et al., 2017).</p>
