Description
Reports of snow depth, new snowfall, and the snow water equivalent of these observations are available from automated networks, and from manual reports taken by volunteer observers.The MADIS snow dataset includes reports from many observing networks run by different "providers". Through the MADIS API, the user can select only a subset of the total by specifying which providers to include or exclude. Examples of automated networks found in the dataset include MesoWest (including SNOTEL and other networks) and RAWS. Manual reports from volunteer observers are found in the CoCoRaHS, CWOP, and GLOBE networks (see the links below).
Geographic Coverage
The geographic coverage of the automated data is the United States. Some of the manual reports taken by CWOP and GLOBE volunteers are global.Data Schedule
Data arrive on a continuous, asynchronous schedule, and newly arriving data are processed every 5 minutes. The data are segmented into hourly files, with the file for hour HH containing data for HH00 through HH59. Many of the manually-taken reports are reported hours, days, even weeks late, so you should set up your ingest schedule based on whether you only need data in near real-time, or on whether you can accept reports that have been made long after the fact.Volume
