Changelog

When we make backward-incompatible changes to the API, we release new, dated versions.

Review the Migration Guide for more details on required changes for an upgrade.

2022Q4

November

  • DATA Evapotranspiration – We've added evapotranspiration data field according to Penman–Monteith FAO56 calculation. This is a big step for our API towards supporting our agriculture customers. :leaves:

  • DATA Historical – We have added four Growing Degree Days data fields to our Historical API with different temperature base and temperature cap values: gdd10To30, gdd10To31 , gdd08To30, and gdd03To25.

  • DATA Core – We have added moon rise and moon set times to our Timeline API. The fields moonriseTime and moonsetTime are available using the 1d time step.

    ,sleetAccumulationLwe,iceAccumulation,and iceAccumulationLwe.

2022Q3

September

  • DATA Core – We have added four Growing Degree Days data fields to our Timeline API with different temperature base and temperature cap values: gdd10To30, gdd10To31 , gdd08To30, and gdd03To25.

August

  • APIHistorical API expansion to 22 years! We now provide historical data from the year 2000 :clock113: This will help conduct climatological research, explore how the weather is changing around the globe, and make predictions for the coming years.

  • DATA Flood – High Resolution (1-km) CONUS Flood Index.

July

  • API New time Formats support for our APIs. We now offer support for string datetime formats in the startTime and endTime API parameters:
    1. "now"
    2. "nowPlusXm/h/d" where X is a decimal number. For example, nowPlus3h will be the time 3 hours from
    now.
    3. "nowMinusXm/h/d" where X is a decimal number. For example, nowMinus15m will be the time 15
    minutes earlier.

  • DATA New Maritime data fields: seaSurfaceTemperature, seaCurrentSpeed, seaCurrentDirection, and tides :ocean:.

2022Q2

June

  • DATA New Historical API cloudCover data field – We now have historical data for cloud cover, globally :cloud: .

  • API New Historical API percentile aggregation. You can request any historical field with the percentile suffix P5, P50, P95. The percentile aggregation will aggregate the data over the area (polygon and polyline) and time :chart-with-upwards-trend: .

  • DATA Wildfire Smoke Index – We now provide wildfire smoke index :fire: on land, globally. The wildfire smoke index conveys the risk that an area may be exposed to elevated particulate matter concentrations (PM2.5) from nearby fires. The new data field returns values between 0 to 5, where 0 indicates there's no risk and 5 indicates the likelihood of extreme smoke concentrations. The new data field is also supported by our Map API and returns tiles over areas that have wildfire smoke.

May

  • API Alerts API - All Clear Duration - We added the ability to define an “all clear duration” which will determine the amount of time for which conditions must be forecasted as unmet for the “all clear” alert to be sent.
  • DATA Hail – We now support real-time and forecast Hail :sparkles: over the US and Canada. The new data field returns 0 when there is no hail and 1 when hail has been detected. The new data field is also supported by our Map API and returns tiles over areas that have hail.

April

  • DATA Aviation – We added a new data layer section for aviation. We now provide METAR, TAF, ASOS, and other airport weather observations directly through our Timeline API.
  • SLO Status Page – We launched a new status page to publish outages and notify our customers when our services are unavailable.

2022Q1

March

  • API Timeline API - We've extended our timeline data from -48 hours to -7 dyas. You can now have -7 days in the past and 14 days forecast with a single API call.

February

  • API Bulk Location Tags - We've added the option to add or remove 100 tags for multiple locations in one bulk request.
  • API Bulk Insights Tags - We've added the option to add or remove 100 tags for multiple insights in one bulk request.
  • DATA Core – Introducing three new data fields: rainAccumulation, iceAccumulation, snowAccumulation, and sleetAccumulation. The new fields can be used by our Create an Insight API to monitor specific precipitation accumulation types over a point location, polygon, and polyline.
  • Documentation - Documentation portal functional improvements including dynamically generate code in real time, interactive API logs experience, API calls history, and support for more code languages.

January

  • API Overview ] – New API Product :rocket: - With the new synchronous historical API you can now query for historical data, going back to January 1st, 2015.
  • DATA Core – Introducing four new data fields: rainIntensity, freezingRainIntensity, snowIntensity, and sleetIntensity. The new fields can be used by our Create an Insight API to monitor specific precipitation types over a point location, polygon, and polyline.
