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 …

Yin, Liu Develop Optimally Blended Drought Index

February 22, 2019

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 …

Yatheendradas, Liu’s Assimilation Efficiency article in EOS Research Spotlight

February 7, 2019

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 …

Yatheendradas Published in Computational Geosciences

January 18, 2019

ESSIC Assistant Research Engineer Soni Yatheendradas recently published a paper titled “Bayesian analysis of the impact of rainfall data product on simulated slope failure for North Carolina locations” in Computational Geosciences. The study simulated slope failures using a physically-base model with three different precipitation data products as input. All three products performed well, though at the highest elevations the TMPA and NLDAS-2 based results degraded, while the quality of …
