Fangfang Yu Leads Global Space-based Inter-Calibration System Meeting

March 30, 2022

The 2022 Annual Global Space-based Inter-Calibration System (GSICS) meeting was successfully held online on 10 March 2022 and 14 – 18 March 2022. Dr. Fangfang Yu, ESSIC/CISESS Associate Research Scientist and new presiding chair of the GSICS Research Working Group (GRWG), led the effort to organize the meeting with the help of the GSICS Coordination Center (GCC) and GRWG members.

Growing This Plant Could Mitigate Climate Change in the Midwest

March 25, 2022

A new study including ESSIC scientist Xin-Zhong Liang has discovered that growing Miscanthus + giganteus, a type of perennial biomass crop, has a strong likelihood of significantly lowering regional summer temperatures and the vapor-pressure deficit, while increasing rainfall and overall crop productivity. This work was published in Global Change Biology-Bioenergy with Liang serving as Lead Principal Investigator. The first author, Yufeng He, is a former ESSIC Postdoctoral Associate.

Giant Lenticular Cloud, Seen from the Ground & in Space!

March 11, 2022

A giant lenticular cloud was seen in Maryland at about 5:50 pm on March 1st, 2022. ESSIC/CISESS Post-doctoral Associate Daile Zhang captured the cloud in Figure 1 below and a video posted to her Twitter account. GOES-East also detected the cloud as seen in Figure 2 and 3.

Exploring Super Resolution Satellite Images with Artificial Intelligence

February 28, 2022

NOAA Center for Satellite Applications and Research (STAR) scientists are exploring new capabilities of enhancing satellite images with artificial intelligence (AI) so that moderate resolution images could be enhanced to include more detailed features with high resolution.

Leveraging Machine Learning to Improve Sea Surface Temperature Retrievals

February 28, 2022

The Microwave Integrated Retrieval System (MiRS) Science Team has published a paper in IEEE Journal on Selected Topics in Applied Earth Observations and Remote Sensing (JSTARS) titled “Improvement of MiRS Sea Surface Temperature Retrievals Using a Machine Learning Approach”.

An Improved Method for VIIRS Radiance Limit Verification and Saturation Rollover Flagging

February 25, 2022

Wenhui Wang, ESSIC/CISESS Associate Research Scientist, is first author on a new paper titled “An Improved Method for VIIRS Radiance Limit Verification and Saturation Rollover Flagging” recently published in IEEE Transactions on Geoscience and Remote Sensing. Other ESSIC/CISESS scientists credited on the project include Slawomir Blonski, Bin Zhang, and Sirish Uprety.

Figure 1. (a) Horizontal distribution of MiRS NOAA-20 ATMS TPW for all of 2019, (b) meridional distribution of statistics for MiRS NOAA-20 ATMS TPW versus ECMWF (black) and GDAS (red) (dots are bias (mm) and lines are standard deviation (mm)): number of pixels are more than 1.2 million for each latitude between 80°S and 80°N. Beyond this area the number of pixels decreases significantly. Global distribution of bias (mm) of (c) MiRS NOAA-20 ATMS TPW – ECMWF TPW, (d) MiRS NOAA-20 ATMS TPW – GDAS TPW, standard deviation (mm) of MiRS NOAA-20 ATMS TPW versus (e) ECMWF TPW and (f) GDAS TPW. All results are for combined ascending and descending orbits in 2019. The red box (120°W ∼ 150°W & 8°N ∼ 12°N) in each plot indicates an area typically characterized by strong convection (CONV area) and the black box (100°W ∼ 120°W & 5°S ∼ 12°S) indicates an area typically dominated by subsidence (SUBS area).

In-Depth Evaluation of MiRS Total Precipitable Water From NOAA-20 ATMS

February 16, 2022

The MiRS Science Team, composed of ESSIC/CISESS scientists Yong-Keun Lee and Christopher Grassotti, as well as NOAA STAR scientist Mark Liu, published a paper this week titled “In‐Depth Evaluation of MiRS Total Precipitable Water From NOAA‐20 ATMS Using Multiple Reference Data Sets” in Earth and Space Science. Lee was the first author of the study.

Watch the Longest Lightning Flash Ever

February 16, 2022

The ESSIC/CISESS Geostationary Lightning Team team, which includes Scott Rudlosky and Daile Zhang, have released a new ArcGIS Story Map via the NOAA GeoPlatform titled “Longest Lightning Flash Ever?”. This website provides stunning visualizations of a recently documented world record flash that covered a horizontal distance of 768 km (477.2 miles) on April 29, 2020. This is equivalent to the distance between New York City and Columbus, Ohio. This flash was recently certified as the longest single flash world record, as covered in an ESSIC press release.
