Top of the atmosphere normalized radiance (a), and degree of linear (b) and circular (c, multiplied by 103) polarization as a function of aerosol optical depth (AOD) at 550 um for selected near-UV to near-IR wavelengths angle 142.5 (SZAD40, VZAD40, RelAzimD120).

Circular Polarization in Atmospheric Aerosols

ESSIC Scientist Santiago Gasso is first author on a new paper in Atmospheric Chemistry and Physics that provides an overview of aerosol sources of circular polarization in the atmosphere and discusses possible remote sensing signatures.

Florida Flood Maps for Hurricane Ian

Hurricane Ian made landfall in Florida on the afternoon of 9/28/2022 as a massive Category 4 storm and brought record-setting winds. As of 10/4/2022, at least 105 people have been reported as casualties of Hurricane Ian, 55 of which in Lee County, Florida. Even more people are without power or their home. The NOAA STAR Flood team has produced VIIRS Flood maps, Sentinel-1 SAR Flood maps, and blended Flood maps to report the flood extent due to Hurricane Ian.

Figure: (Top panel) Rain-Rate predicted by eTRaP and observed by MRMS. (Bottom panel) Scatter plot and estimation metrics for Tropical Storm Fiona between September 18, 2022 12 UTC to September 19, 2022 12 UTC.

NPreciSe Evaluation of eTRaP during Tropical Storm Fiona

Tropical Storm Fiona struck Puerto Rico on September 17-18, 2022 causing catastrophic floods and leaving most of the island with a major power outage. Fiona is the first Atlantic storm this season to cause a major disaster. NPreciSe (NOAA Satellite Precipitation Validation System) led by the CISESS science team (Malar Arulraj, Veljko Petkovic, Ralph Ferraro, and Huan Meng), evaluated the performance of the Ensemble Tropical Rainfall Potential (eTRaP) forecasts during this event, using a recently added Multi-Radar/Multi-Sensor (MRMS) observation product over Caribbean Islands.

Extreme Wave Heights in the Bering Sea from Remnants of Typhoon Merbok

Coastal Alaska was devastated by flooding due to the remnants of Typhoon Merbok (Figure 1a) on September 17, 2022. Storm surge flooded communities along 1,000 miles (1,609 km) of Alaska’s west coast, damaging homes, submerging roads and triggering evacuations. Satellite measurements recorded 17 observations of significant wave height exceeding 14 m (46 feet) on September 16-17 2022 (Figure 1b, dark red dots). Such a sea state is defined as “phenomenal” by the World Meteorological Organization (WMO). During the 48-hour period, 5% of all satellite radar altimeter observations in the Bering Sea exceeded 9m (30 ft), defined as “very high” seas by the WMO (Figure 1c) and 19% of observations exceeded 6m (20 ft), WMO “high” seas.
