We will implement all the principles embodied in the NASA Earth science data policy. During the field campaign we will employ two matched teams of “data wranglers,” one for the ground data and one for the airborne data. Since both types of data will be collected during the day, the wranglers will work through the night. They will perform a QA/QC check of the data to ensure there are no problems in collection, then run the data through preliminary spatial extrapolation models (ground data) or reduction models (remote sensing data). They will then do a rapid comparison of the two data streams to identify areas where interpretations are uncertain or additional ground data are needed. By the next day, they will be able to provide feedback to the ground and airborne team leaders so that adjustments can be made as needed in the following day’s operation. SnowEx will use this proven approach to help lower the risk of ending up with missing or unusable data.
After the campaign, SnowEx will utilize a standard mission Level 1 Requirement for NASA projects.
- The SnowEx Investigators shall produce the standard science data products to be specified for each sensor.
- The SnowEx Investigators' standard science data products and associated metadata shall be made publicly available. The science data product formats will conform to one of the ESD-approved Data System Standards. Data will also have accompanying spatial, temporal and product metadata that conform to ESD-approved metadata specifications.
- Science algorithms and calibration procedures used to generate the standard data products (to be specified for each sensor) shall be described in documents that are accessible to users.
- By the Investigation Closeout, SnowEx Investigators shall deliver all data products, along with the scientific algorithm software, coefficients, and ancillary data used to generate these products, to a designated NASA Earth Science Division-assigned Data Center.
- All terms and conditions of the transfer of data products and associated information to the designated NASA Earth Science Division-assigned Data Center shall be documented in a Data Management Plan.
See a summary of SnowEx17 data that are currently available from NASA Distributed Active Archive Center (DAAC) at National Snow and Ice Data Center (NSIDC). Note that the SnowEx Airborne Snow Observatory (ASO) data are also available from NSIDC. The CAR snow BRDF data is archived at Goddard Earth Sciences Data and Information Services Center (GES DISC).
