RapidScat data flow at PO.DAAC has been suspended since 17 February 2016, corresponding to the last day of observational data received for 10 February 2016 (note: there is a 7-day latency gap for all RapidScat data received by PO.DAAC), extending through to orbital rev number 7860, 21:25 UTC.
The cause of the data outage, which is still ongoing, is due to a disruption to the instrument calibration that has resulted in a negative wind speed bias of 1 m/s. The calibration appears to have changed after the transition to the latest low SNR state on 10 February 2016. The RapidScat Science Data Systems team is working on recalibrating the data as well as completing their diagnosis as to the nature of the sudden calibration change.
Datasets impacted include L2B, L2A (25-km and 12.5-km), and L1B.
Data users are asked to remain patient while the RapidScat recalibration is underway, which is expected to take at least one more week before nominal data flow is restored to PO.DAAC.
Concerned data users who are not currently registered with the PO.DAAC email list are encouraged to register to receive timely data announcement updates via email by contacting podaac@podaac.jpl.nasa.gov.
