Virtual Workshop on “Precipitation Estimation from LEO Satellites: Retrieval and Applications”

March 8, 2023

Last week, NOAA NESDIS held a two-day virtual workshop on “Precipitation Estimation from LEO Satellites: Retrieval and Applications”. The workshop was organized by CISESS Consortium Scientist Kuolin Hsu at University of California, Irvine through a task funded by NESDIS’ Joint Polar Satellite System (JPSS) Program Office. The primary goal of the workshop was to determine future satellite observation requirements for global precipitation. The workshop had nearly 100 participants for each of the four sessions that spanned two days.

Atmospheric Sounding from the CubeSat TROPICS Mission

February 13, 2023

ESSIC/CISESS scientists John Xun Yang, Yong-Keun Lee, and Christopher Grassotti are co-authors on a new paper titled “Atmospheric humidity and temperature sounding from the CubeSat TROPICS mission: Early performance evaluation with MiRS” in Remote Sensing of Environment.

[VIDEO] Zhang helps the Lake-Effect Electrification (LEE) Field Campaign

February 1, 2023

Daile Zhang helped the NSF-funded LEE field campaign in Oswego, NY this week. The LEE project aims to study the electrification mechanism of the lake effect snowstorms in the Great Lake area. This is the first time that scientists have conducted such an experiment. Daile helped launch the balloon and electric field mill in the field, testing and preparing for the electric field mill, and making connectors in the lab.

ESSIC/CISESS at the AMS Annual Meeting

He presented research on the relationship between lightning observations from the Geostationary Lightning Mapper and the circuitous paths aircraft have to take to avoid turbulent thunderstorms. GLM observations, showing the unique spatial footprint of lightning flashes with rapid updates, play a critical role in enhancing the forecasts of operational aviation meteorologists who are in direct communication with Air Traffic Control and pilots during severe weather events.

Evaluation of Snowfall Retrieval Performance of GPM Constellation Radiometers Relative to Spaceborne Radars

January 4, 2023

Several current and former ESSIC/CISESS scientists are co-authors on a new paper in Journal of Hydrometeorology titled “Evaluation of Snowfall Retrieval Performance of GPM Constellation Radiometers Relative to Spaceborne Radars”. Former ESSIC scientist Yalei You was first author on the paper. Current ESSIC/CISESS scientists on the paper are Veljko Petkovic, Lisa Milani, John Yang, and Guojun Gu.

Daile Zhang Speaks at the International Conference on Lightning Protection

December 19, 2022

ESSIC/CISESS Scientist Daile Zhang is a coauthor of a presentation that was given at the 36th International Conference on Lightning Protection in Cape Town, South Africa during October 2-7, 2022. She has published a conference paper, which was presented by the co-author Ron Holle, a former meteorologist for Vaisala as well as NOAA. The paper is titled “The Epidemiology of Lightning in Mainland China – A Review of Two Datasets from the 1950s to 2018.”

“Unseen Heroes” Awards for the S-NPP CDP Reset Recovery Team

December 19, 2022

On December 6, the NOAA Joint Polar Satellite System (JPSS) Program Office announced that the “Unseen Heroes” award would go to the Central Data Processor (CDP) Reset Recovery Team. It was given “in recognition of efforts to restore the Suomi-National Polar-Orbiting Partnership (S-NPP) satellite instruments after a central data processor reset.” This was a major effort in collaboration between the JPSS SDR teams and OSPO to recover the SNPP satellite after the instrument entered “Sun-pointing mode,” leading all of the onboard JPSS instruments to go offline and require restarting and revalidation. The CISESS and Consortium Scientist awardees were:

ESSIC/CISESS Lightning Team at 2022 Mid-Atlantic ChaserCon

November 16, 2022

The ESSIC/CISESS Lightning Team members Guangyang Fang and Daile Zhang recently attended the 2022 Mid-Atlantic ChaserCon, a conference for meteorologists at National Weather Service, broadcast meteorologists, emergency managers, storm chasers and other professional and amateur meteorologists across the great Mid-Atlantic area to network and discuss local severe storms and promote ideas to raise public awareness of severe weather and emergency management. Accompanying them were Undergraduate Research Assistants Alex Friedman, Domenic Brooks, and Samantha Smith as well as an AOSC grad student Alvin Cheung.
