GPM Ground Validation Snow Depth Monitoring System OLYMPEX V1

The GPM Ground Validation Snow Depth Monitoring System OLYMPEX dataset consists of snow depth, temperature, and relative humidity measurements which were collected using snow depth poles, time lapse cameras, temperature/relative humidity sensors, and manual snow surveys. This dataset was collected during the GPM Ground Validation Olympic Mountain Experiment (OLYMPEX) held on the Olympic Peninsula in the Pacific Northwest of the United States. The analyzed data files are available in netCDF-3 data format. The dataset includes the individual camera photos of snow poles taken hourly during the field campaign, provided as JPG images. There are up to 3 cameras/poles per study site location. In addition, a Microsoft Excel data file contains results of a manual snow survey taken on the specific days of the Airborne Snow Observatory OLYMPEX overflights. In total, measurements contained in this dataset extend from September 5, 2014 through August 20, 2016, but the primary field campaign data were collected during the fall 2015 to spring 2016 time period.

Each data record contains a variable indicator to identify data as snow on the ground on the last day of the month (centimeters) or total snowfall for the month (millimeters). A list of stations, with latitude and longitude to hundredths of a degree, is included in documentation for this data set.

Rand Corporation Mean Monthly Global Snow Depth, Version 1

This data set provides monthly snow depth for the entire globe (excluding Africa and South America) from 1950 to 1976. All available monthly snow depth climatologies were integrated by the Rand Corporation in the early 1980s into one global digital data set gridded at 4 degree latitude x 5 degree longitude.
