Alt Tag: Radiometer percent RFI, April 2012.Map Description:
Radiometer RFI in the northern hemisphere at 1.413 GHz, the frequency of the three radiometers on board Aquarius, for April 2012. Each data point is obtained by averaging radiometer measurements acquired over a 1.44-second time window. The color scale indicates the percentage of these measurements that are suspected to be corrupted by RFI within the time window (and are thus not used to calculate salinity). Red colors indicate areas that have over 80% of their sampled data flagged for RFI. Dark blues show relatively little RFI, less than about 10% of samples are flagged in these regions.
