Characterizing Congo Basin Rainfall and Climate Using Tropical Rainfall Measuring Mission (TRMM) Satellite Data and Limited Rain Gauge Ground Observations
(American Meteorological Society, 2014)uantitative understanding of Congo River basin hydrological behavior is poor because of the basin?s limited hydrometeorological observation network. In cases such as the Congo basin where ground data are scarce, satellite-based ... -
Causes and Implications of Extreme Atmospheric Moisture Demand during the Record-Breaking 2011 Wildfire Season in the Southwestern United States
(American Meteorological Society, 2014)n 2011, exceptionally low atmospheric moisture content combined with moderately high temperatures to produce a record-high vapor pressure deficit (VPD) in the southwestern United States (SW). These conditions combined with ... -
Assessing the Vegetation Condition Impacts of the 2011 Drought across the U.S. Southern Great Plains Using the Vegetation Drought Response Index (VegDRI)
(American Meteorological Society, 2014)he vegetation drought response index (VegDRI), which combines traditional climate- and satellite-based approaches for assessing vegetation conditions, offers new insights into assessing the impacts of drought from local ... -
Velocity–Azimuth Display Analysis of Doppler Velocity for HIWRAP
