July 25, 2019

Earlier this month, Geophysical Research Letters published an article co-authored by ESSIC/CISESS Assistant Research Scientist Yalei You and Faculty Specialist Jun Dong as well as Visiting Research Scientist Huan Meng and Visiting Assistant Research Scientist Scott Rudlosky. Titled “Time‐Lag Correlation Between Passive Microwave Measurements and Surface Precipitation and Its Impact on Precipitation Retrieval Evaluation”, the study showed a time lag between satellite radiometer-retrieved …

ESSIC/CICS Scientists Travel to Italy for Satellite Observation Meeting

March 15, 2019

Last week was the annual meeting of the Global Space-based Inter-Calibration System (GSICS), an international collaborative effort to monitor, improve, and harmonize observations from the Global Observing System weather and environmental satellites. The meeting, held in Frascati, Italy, included a “Mini-Conference” on calibration activities outside of GSICS as well as reports, briefs, and discussions on the GSICS Research Working Group, GSICS Data management Working Group, and GSICS …

ESSIC / CICS-MD Scientists Published on the GOES-16 Advanced Baseline Imager

November 6, 2018

ESSIC / CICS-MD Visiting Associate Research Scientists Fangfang Yu and Zhipeng Wang were recently published on a new CICS Task entitled “Calibration Support for Advanced Baseline Imager (ABI)”. The Advanced Baseline Imager is an instrument onboard the GOES-R satellites that images Earth’s weather, oceans and environment. The GOES-R ABI has presented many new challenges in radiometric calibration, or calibrating image data to radiance, reflectance, or brightness temperatures. These are …

Wang and Zhang published in Journal of Geophysical Research

December 13, 2017

ESSIC researchers Likun Wang and Bin Zhang are authors of a new study published in the Journal of Geophysical Research Atmospheres regarding improvements in geolocation assessment for Cross-track Infrared Sounder (CrIS) scan angles. The new method reduces geolocation errors in the data. Data quality of the CrIS is essential for atmospheric and temperature profiles, trace gas measurements and model assimilation….
