Multi-Scale Observations Preceding the Moore, OK Tornado

With contributions from Patrick Meyers (CICS-MD/ESSIC)
Extreme weather events such as the recent Oklahoma tornados consistently remind weather and climate scientists of the importance of their work.  Fortunately, the United States has a dense network of observing systems coupled with a dedicated group of researchers and forecasters who use these systems to better understand, predict, and analyze these dangerous natural forces.  Collaborations between physical and social scientists have …

Global Flood Working Group

By: Robert Adler

With increasing observation and modelling capacity, scientists are now able to produce relevant information on flood disasters more rapidly and with sufficient accuracy and precision for a variety of humanitarian response tasks.  Several research groups across the world have set-up pre-operational or operational monitoring systems as an outcome of their research.

Since floods are complex phenomena that affect societies in many different ways, there is not one system that can completely meet

Obama Vs. Romney: Climate Change

In tonight's presidential debate, republican candidate Mitt Romney has room to attack and to fail on the issue of climate change against President Barack Obama.

So far, both candidates have kept their positions on the climate and our nation's effect on global warming rather silent during the election season. However, as the first national debate kicks off tonight, republican strategists are predicting Romney may take the stance that the Earth is warming due to human activity and deny his links

223 – Global Precipitation Analysis
Principal Investigator(s): Robert F. Adler, Guojun Gu

The objective is to analyze precipitation data from the Global Precipitation Climatology Project (GPCP) and other sources to understand interannual to interdecadal/long-term variations in global and regional precipitation.

220 – Retrievals and Analyses of Global Aerosol Properties
Principal Investigator(s): S-H. Wang

Aerosols affect Earth’s energy budget by scattering and absorbing radiation (the “direct effect”) and by modifying microphysical and radiative properties of clouds (the “indirect effect”). The complex spatial, temporal, chemical composition, physical size and shape, and optical characteristics of atmospheric aerosols cause large uncertainties in the estimation of aerosol effects on climate. To lessen the uncertainties, remote sensing and in-situ measurements as observational approach providing essential information. The NASA/GSFC SMART-COMMIT (Surface-sensing Measurements for Atmospheric Radiative Transfer – Chemical, Optical, and Microphysical Measurement of In-situ Troposphere) mobile observatory has conducted more than 10 worldwide field campaigns in the past 10 years. The surface remote sensing and in-situ technologies were applied to study aerosol properties using SMART-COMMIT database. We integrate surface radiation measurement, satellites data, and radiative transfer model to understand the global aerosol properties and regional radiative impact of aerosols.
