Aquarius Official Release Level 3 Rain-flagged Sea Surface Salinity Standard Mapped Image 28-Day Running Mean Data V5.0

Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/aqr50-3yrce

Aquarius Level 3 sea surface salinity (SSS) rain-flagged standard mapped image data contains gridded 1 degree spatial resolution SSS averaged over daily, 7 day, monthly, and seasonal time scales.

Description

This particular data set is the 28-Day running mean, rain-flagged rain-flagged sea surface salinity product for version 5.0 of the Aquarius data set. The instrument consists of three radiometers in push broom alignment at incidence angles of 29, 38, and 46 degrees incidence angles relative to the shadow side of the orbit.

Footprints for the beams are: 76 km (along-track) x 94 km (cross-track), 84 km x 120 km and 96km x 156 km, yielding a total cross-track swath of 370 km. The radiometers measure brightness temperature at 1.413 GHz in their respective horizontal and vertical polarizations (TH and TV). A scatterometer operating at 1.26 GHz measures ocean backscatter in each footprint that is used for surface roughness corrections in the estimation of salinity.

The scatterometer has an approximate 390km swath.
