More accessible climate data

We processed the Localized Constructed Analogs (LOCA) for North America and the Global Daily Downscaled Projections (NEX-GDDP), and two carbon scenarios (RCP 4.5 and RCP 8.5) to give you access to low temperature, high temperature and precipitation data from 1950 to 2100. With 22 climate indicators for over 1,000 U.S. locations, you can be sure to find the right information.

Extreme Precipitation Events
Extreme Precipitation Events

The number of times where the daily precipitation exceeds the 95th percentile observations for the years 1960-1995. This indicator could be used to estimate whether an area will become more prone to flash floods.

Average High Temperature
Average High Temperature

The daily high temperature, averaged over a specified time period. This indicator could be used to estimate climate trends over long periods of time.

Heat Wave Incidents
Heat Wave Incidents

Counts the days the daily high temperature exceeds 5˚C above historic average high temperature norms for at least 5 consecutive days. Important for health and emergency services planning.

Yearly Dry Spells
Yearly Dry Spells

Counts when there are 5 or more consecutive days without precipitation. This indicator could be used to estimate future drought frequency.

Frost Days
Frost Days

Count of days where the daily low temperature is below 0˚C (32˚F). This indicator could be used to approximate agricultural and natural resource impacts.

Introducing Temperate

We built an easy-to-use application using the Climate API called Temperate. Temperate puts climate data into context and helps planners develop their vulnerability assessment and action plan. Designed for small- and mid-sized cities with limited resources, Temperate offers customized consulting assistance from ICLEI-USA.
