Data from many surface networks are available to the atmospheric science and hydrology communities. Select a link for more detailed information on that network, or see the summary table below for an overview of available observations.

Near real-time/archived data available for air temperature (AirT); relative humidity (RH); wind (speed, direction, sometimes gust); precipitation (Ppt); snowfall and snow depth (Snow), solar radiation (Solar); barometric pressure (Press); soil temperature at various levels (SoilT); soil moisture at various levels (SoilM); and derived dew point temperature (Td). The number of stations are approximate for each network and only account for the continental US.
