SnowEx Data Pledge

The NASA SnowEx program is committed to creating extensive ground-based and remote sensing snow calibration and validation data products for all SnowEx field campaigns. To address the human uncertainties, an inherent trade-off to data collection efforts of this size, we ensure all core data follow a standard sampling protocol and are reviewed for standardization following the data collection period. Objective data standardization criteria are documented during the data delivery process and published with the data products. This ensures data provenance and transparency for the legacy data sets created to improve the remote sensing of snow.

Public Data

NSIDC

SnowEx Campaign data is publicly available through the NASA DAAC at the National Snow and Ice Data Center (NSIDC) in Boulder, Colorado. Data are available to anyone at no cost, as is the case with all NASA data. Available data products are searchable by campaign year. You can also browse recently published data by visiting the Data Announcements page, a product from NSIDC to share news and tips with data users.
