SSM/I-SSMIS Brightness Temperature Data Availability

The tables on this Web page provide the data availability and missing dates for two brightness temperature data sets available from NSIDC. One data set is in the Equal-Area Scalable Earth Grid (EASE-Grid) projection, and the other is in the Polar Stereographic projection. The data sets are the following:

Table 1 provides the data availability and Table 2 provides a list of missing dates.
