NOAA Daily Optimum Interpolation Sea Surface Temperature (DOISST) Version 2.1

August 24, 2021

ESSIC/CISESS Visiting Research Scientist Tom Smith is coauthor of an article on DOISST v.2.1 coming out in the September 2021 issue of the Journal of Climate. The paper, titled “Assessment and Intercomparison of NOAA Daily Optimum Interpolation Sea Surface Temperature (DOISST) Version 2.1”, shows how the improved NOAA operational analysis compares to several other available analyses.

Figure: This is a precipitation event on 29 August 2020 over the Pacific Ocean near the lower California peninsula. (a) the cross-track radiometer precipitation data, (b) the conical scanning radiometer precipitation data, (c) the reference data for the event, and (d) the “morphed” radiometer precipitation data. The box shows the area of improvement due to morphing.

Improving Satellite Precipitation Retrieval

August 24, 2021

ESSIC/CISESS Scientists Yalei You, John Xun Yang, and Jun Dong have a new article on using “morphing” to improve rain data from cross-track scanning radiometers. The paper, titled “Improving Cross-track Scanning Radiometers’ Precipitation Retrieval over Ocean by Morphing”, is in press at the Journal of Hydrometeorology.

Figure. Comparing different algorithms for estimating NEDT against TVAC measurement. The new algorithm out-performs traditional algorithms of EUMETSAT, UK MetOffice and NOAA. While the 183 GHz is prone to 1/f noise, the new algorithm produces an accurate estimate of NEDT and is superior to traditional algorithms.
