CoCoRaHS Network Observations | Community Collaborative Rain, Hail, and Snow Network
CoCoRaHS is a unique, non-profit, community-based network of volunteers of all ages and backgrounds working together to measure and map precipitation (rain, hail and snow). To join the CoCoRaHS volunteer program, see cocorahs.org
Observation History
Click on the "City, ST" (3 days of obs) or "Past 30 Days" (30 days of obs) for observations, as well as interactive temperature, wind, and precipitation graphs. For observations beyond 30 days, see the Iowa Environmental Mesonet by clicking on the "IEM" link. Past radar data is available on the IEM's Radar Page.
Visible - This image is taken in visible light, or what the human eye would see from the satellite. Sunrise and sunset can be tracked in this image.
Infrared - This image is taken in the infrared band of light and show relative warmth of objects. Colder objects are brighter and warmer objects are darker. Lower layers of clouds, generally warmer and lower in altitude, are colored gray. Colder and generally higher clouds tops are highlighted in colors. Infrared imagery is useful for determining cloud features both at day and night.
Water Vapor - This image is taken using a wavelength sensitive to the content of water vapor in the atmosphere. Bright and colored areas indicate high water vapor (moisture) content (colored and white areas indicate the presence of both high moisture content and/or ice crystals). Black and brown areas indicate little or no moisture present. Water vapor imagery is useful for both determining locations of moisture and atmospheric circulations.
