RSS CCMP V3.1 6-hourly surface winds (Level 4), Lon+/-180

RSS VAM 6-hour analyses using ERA-5 wind reanalyses as background. Satellite winds (vector and scalar) are assimilated using a variational analysis identical to that used in CCMP V1.1. The ERA5 winds are adjusted to match winds from scatteromters before use in the analysis.
