Who We Are

The Delaware Environmental Observing System (DEOS) is a support tool for decision makers involved with emergency management, natural resource monitoring, transportation, and other activities throughout the State of Delaware. Our primary goal is to provide state agencies and the citizens of Delaware with immediate information about environmental conditions in and around the State. DEOS also archives data for historical environmental studies and research.

Popular Products

The GeoBrowser is a tool that provides users a way to access DEOS data through a geographic framework. In the GeoBrowser, you can select stations to see current conditions and access daily and monthly summaries. You can also view the latest weather radar and warnings from the National Weather Service.

DEOS provides real-time snow depth data for 12 locations across Delaware. Data are reported as 48-hour snow accumulation values, which represents the largest difference between the maximum and minimum snow depth in the most recent 48 hour period.

Agriculture/Irrigation Summaries are generated for most stations in the DEOS network. Data types in this summary include reference evapotransipiration, growing degree days, soil temperature, and soil moisture.

DEOS Network Station Updates:

1/27/10 - DWAR (Harbeson, DE-REC) is temporarily offline due to communications repairs.

Upcoming Station Move
Added 01/27/10

On January 28th, 2010, DEOS will be moving the weather station currently located at the University of Delaware - Wilmington Campus to its new home at Winterthur in Greenville, DE. This move was required in order to accomodate the construction of a retention feature in the area where the station is currently located. Its new location was chosen to ensure quality station siting characteristics and to keep the station in a reasonably consistent spatial location within the DEOS network.
