Data Services


CLIMOD has a user friendly interface that allows you to quickly access temperature, precipitation, and snowfall data, perform analyses, and create temperature and precipitation graphs.

ACIS Web Services

Download daily data from thousands of stations available through ACIS. ACIS Web Services requires a more advanced understanding of how online API's operate. Documentation is available.


Download daily data from thousands of stations available through ACIS. scACIS is like CLIMOD, but provides more advanced functionality.


The Automated Weather Data Network is a partnership between state mesonets and the HPRCC. Daily and hourly data are available across a 10 state region.

County Level Data

County-wide 30-year averages for temperature and precipitation for all the counties in the High Plains Region.

Station Report

Create printable reports for any station in ACIS.

Maps and Graphs

ACIS Climate Maps

Browse thousands of temperature maps, degree day maps, and precipitation maps. Departure from normal maps also included.

ACIS Climate Maps GIS Portal

Find shapefile versions of the ACIS Climate Maps. Shapefiles are available as filled contours (polygons), or as point data.


Check out 1-day and 7-day maps from the AWDN. Popular maps include soil temperature and evapotranspiration.

Climate Atlas

50 years of data were used to create this atlas. Popular maps include first/last freeze and precipitation frequencies.

Climate Summary Gauges

Quickly view how this month, season, and year compares to the past. Temperature, precipitation, and select extremes are available.

Heat Index Maps

Heat index climatology maps for different thresholds during the summer months are available for the plains portion of the High Plains region. Nearly 40 years of data were used in the creation of these maps.

Lightning Climatology

Monthly and annual maps of mean flash density, broken into positive and negative flashes, are available. Nearly 20 years of data were used to create this lightning climatology for the Missouri River Basin region.

Normals Maps

A variety of monthly and annual maps based on the 1981-2010 normals are available for the High Plains region.

Soil Temperature Climatology

This soil temperature climatology gives the average Julian (and calendar) day at which the 5-day running average soil temperature at 4 inches reaches specific temperature thresholds conducive for crop and agronomic seed germination.

Spatial Climate Analysis

View a GIS version of the ACIS Maps on a web map. Click on any station point to graph station data, or use the Grid Point Inspector to analyze any location in the lower-48 states.

Station Data Explorer

Create static and/or interactive graphs for thousands of stations across the country. Precipitation and snowfall accumulation graphs are available within this tool.

Station Tool

Special Projects

Agro-Climate Tools

This suite of tools is your source for weather, climate, drought, and cropping data in the North Central Region. These tools offer a one-stop decision resource for ag advisors, producers, and decision makers.


At the Climate4Cities site, four tools are available for communities to help them explore their local climate conditions and learn how others are planning for climate and climate change.

Custom Climatology Tool

With the Custom Climatology Tool, you can create monthly temperature averages using custom time periods for stations all across the United States. You may use any range of years from 1961 through last year, then download the final values as a CSV file.

Tribal Decision Dashboards

These tools were developed specifically for tribal lands to assist tribal managers with climate monitoring and decision making.

Wind Climatology

Gridded wind climatology from 1985 to 2022. This product displays wind rose, gust hours, and high and low wind months for the selected point.
