Overview

Climate Normals is a comprehensive view of climate patterns over a 20-year period. Using weather data with an hourly temporal resolution, the climate normals calculates and presents data for the period between 2000 and 2020. The data set offers valuable insights into long-term climate trends and patterns, making it an essential tool for businesses, governments, and individuals looking to understand and plan for the future. With its high-resolution data and long-term perspective, Climate Normals is an innovative and powerful resource for anyone interested in understanding and managing the impacts of climate change.

The raw data set for the climate normals is in hourly temporal resolution. For each weather data field, you can choose how to aggregate the daily data, and how to aggregate the 20-years data. For example, for the data field temperature you can request the following fields:

API Field NameDescription
temperatureMinThe normal (average) of daily minimum temperature data over the 20 year period
temperatureMinP5The lowest 5% of daily minimum temperature data over the 20 year period
temperatureMinP50The median of daily minimum temperature data over the 20 year period
temperatureMinP95The highest 5% of daily minimum temperature data over the 20 year period
temperatureAvgThe normal (average) of daily average temperature data over the 20 year period
temperatureAvgP5The lowest 5% of daily average temperature data over the 20 year period
temperatureAvgP50The median of daily average temperature data over the 20 year period
temperatureAvgP95 The highest 5% of daily average temperature data over the 20 year period
temperatureMaxThe normal (average) of daily maximum temperature data over the 20 year period
temperatureMaxP5The lowest 5% of daily maximum temperature data over the 20 year period
temperatureMaxP50The median of daily maximum temperature data over the 20 year period
temperatureMaxP95The highest 5% of daily maximum temperature data over the 20 year period

For accumulated data fields like precipitationAccumulation. The daily aggregation over the raw data set will always be the daily sum: precipitationAccumulationSum and you can choose how to aggregate the 20-years data. For example, for the data field precipitationAccumulation you can request the following fields:

API Field NameDescription
precipitationAccumulationSumThe normal (average) of daily precipitation accumulation data over the 20 year period
precipitationAccumulationSumP5 The lowest 5% of daily precipitation accumulation data over the 20 year period
precipitationAccumulationSumP50The median of daily precipitation accumulation data over the 20 year period
precipitationAccumulationSumP95The highest 5% of daily precipitation accumulation data over the 20 year period
