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 …

ESSIC/CICS Assistant Research Scientists Jifu Yin and Jicheng Liu as well as Post-doctoral Associate Mitchell Schull have a new paper out in Water Resources Research titled “An Intercomparison of Noah Model Skills With Benefits of Assimilating SMOPS blended and Individual Soil Moisture Retrievals”. The paper compares blended and individual microwave satellite soil moisture data from Soil Moisture Operational Product System (SMOPS) and evaluates the benefits of assimilating blended and …

ESSIC/CICS Assistant Research Scientists Jifu Yin and Jicheng Liu have a recent article published in Water Resources Research titled “A Method for Objectively Integrating Soil Moisture Satellite Observations and Model Simulations Toward a Blended Drought Index”. The researchers write about the development of a method to objectively integrate widely available satellite soil moisture retrievals into a single accurate and reliable optimally blended drought index (BDI). Compared to official …

ESSIC Assistant Research Engineer Soni Yatheendradas and ESSIC/CICS-MD Assistant Research Scientist Jicheng Liu recently collaborated on a study titled “The Efficiency of Data Assimilation” published in the EOS Journal Water Resources Research. In the piece, the authors offer a framework to quantify information loss from data assimilation through measuring information in models, observations, and evaluation data. The piece was highlighted in a recent EOS Research Spotlight that details …

November 14th marked The Fifteenth Annual Symposium of the Burgers Program for Fluid Dynamics, an event intended to enhance the quality and international visibility of UMD’s fluid dynamics research and educational programs. ESSIC Research Professor and CICS-MD Director Hugo Berbery was a co-presenter of two presentations with his advised AOSC Graduate Assistants Eli Dennis and Katherine Lukens. Lukens-Berbery presented, “Winter Storm Tracks and Related Weather in the NCEP Climate Forecast …
