Virtual Quality Screening Service (VQSS)
The Virtual Quality Screening Service (VQSS) is a quality-based data filtering and subsetting service.
When working with satellite-based earth science data records users often need to access, understand and apply granule-based data quality information, such as that contained in flags. However, current subsetting technologies and visualization packages generally do not understand how to apply quality information. The Virtual Quality Screening Service (VQSS) address these issues and concerns with an infrastructure to expose, apply, and extract quality screened data through implementations of strategic databases and web services, data discovery, and application of granule-based quality information. This capability has been deployed on datasets from the NASA Soil Moisture Active Passive (SMAP) Mission and Group for High Resolution Sea Surface Temperature (GHRSST) MODIS and VIIRS datasets.
