Recent La Plata basin drought conditions observed by satellite gravimetry
[1] The Gravity Recovery and Climate Experiment (GRACE) provides quantitative measures of terrestrial water storage (TWS) change. GRACE data show a significant decrease in TWS in the lower (southern) La Plata river basin of South America over the period 2002–2009, consistent with recognized drought conditions in the region. GRACE data reveal a detailed picture of temporal and spatial evolution ...
متن کاملSatellite Gravimetry Applied to Drought Monitoring
11.1 INTRODUCTION Near-surface wetness conditions change rapidly with the weather, which limits their usefulness as drought indicators. Deeper stores of water, including root-zone soil wetness and groundwater, portend longer-term weather trends and climate variations ; thus, they are well suited for quantifying droughts. However, the existing in situ networks for monitoring these variables suff...
متن کاملRecent shift from forest to savanna burning in the Amazon Basin observed by satellite
The numbers of fires detected on forest, savanna and transition lands during the 2002–10 biomass burning seasons in Amazonia are shown using fire count data and co-located land cover classifications from the Moderate Resolution Imaging Spectroradiometer (MODIS). The ratio of forest fires to savanna fires has varied substantially over the study period, with a maximum ratio of 0.65:1 in 2005 and ...
متن کاملWater Cycle and Climate Signals in Africa Observed by Satellite Gravimetry
The availability of hydrologic data is an important step for hydrological modeling and water resource management in the world. Unfortunately, the in situ observations with the right characteristics are very sparse globally, particularly in Africa. Understanding the climate variability of Africa and its prominent role as the heat engine of the global climate system is one of the key goals in cli...
متن کاملGeneration of Daily Synthetic Precipitation Series: Analyses and Application in La Plata River Basin
Precipitation analysis is embedded in a range of important hydrological studies for hydraulic works construction and maintenance. However, flaws and limitations in records are obstacles often encountered by researchers. One feasible solution for overcoming these obstacles is to generate synthetic series. The main objective of this work is to structure and validate a model for generating synthet...
