GOES-PRWEB BACK ONLINE


GOES-PRWEB is back online.  An error in NOAA’s Advanced Hydrologic Prediction Service (AHPS) precipitation data has been corrected.  Sorry for the inconvenience.

Puerto Rico’s NEXRAD Doppler Radar was severely damaged during Hurricane Maria.  Until the radar has been repaired, NOAA AHPS is using gridded precipitation from the Hydro Estimator satellite product as the source of gridded precipitation.

GOES-PRWEB results are available at the following links:

Estimates

The WSR-88D NEXRAD radar on the Island of Puerto Rico was severely damaged during Hurricane Maria. A full engineering assessment is needed on the current damages to the radar. At this time, it is too early to speculate when the radar will be back online.

Hourly precipitation estimates from the WSR-88D NEXRAD radar were used to compare to ground truth rainfall gauge reports to derive a best quantitative precipitation estimate (QPE) across the island of Puerto Rico.

It is important to be aware of the quality of the data (QPE) for the duration that the radar is out of operation. With the loss of the radar, the QPEs will be based on the Hydro-Estimator (satellite plus rainfall gauge reports).

Studies have shown that algorithms which combine sensor inputs — radar, gauge, satellite — yield more accurate precipitation estimates than those which rely on a single sensor (i.e. radar-only, gauge-only, satellite-only).
