Zhou and Yang Published on New ATMS Geometric Calibration Based on Lunar Images

ESSIC/CISESS Scientists Jun Zhou and Hu Yang recently published an article in the journal Atmospheric Measurement Techniques titled “A Study of a Two-Dimensional Scanned Lunar Image for Advanced Technology Microwave Sounder (ATMS) Geometric Calibration”. The article describes a new technique they developed to validate the on-orbit beam pointing accuracy of the Advanced Technology Microwave Sounder (ATMS) on NOAA-20 by using a 2D scanned lunar image captured during a spacecraft pitch-over …

School of Public Health/ESSIC Study Finds Climate Change Linked to Seasonal Allergies

Climate change might be worsening your spring allergies, reports a new study from University of Maryland researchers including ESSIC Professor Raghu Murtugudde. Using data from the National Aeronautics and Space Administration’s Moderate Resolution Imaging Spectroradiometer (MODIS), the researchers calculated the median spring start date (the “start-of-season” date) for each county in the contiguous US between 2001–2013.  This data was then compared with findings from the National …
