Development of Integrated Crop Drought Index by Combining Rainfall, Land Surface Temperature, Evapotranspiration, Soil Moisture, and Vegetation Index for Agricultural Drought Monitoring

Development and evaluation of Soil Moisture Deficit Index (SMDI) and Evapotranspiration Deficit Index (ETDI) for agricultural drought monitoring

Drought is one of the major natural hazards that bring about billions of dollars in loss to the farming community around theworld each year. Drought is most often caused by a departure of precipitation from the normal amount, and agriculture is often the first sector to be affected by the onset of drought due to its dependence on water resources and soil moisture reserves during various stages ...

Drought Determination by Using Land Surface Temperature and Normalized Difference Vegetation Index

Today, many places of different locations on Earth especially semi-arid areas face the risk of desertification due to severe drought. However, the very basic data required for the analysis is unavailable for the regions without a meteorological station. In this case, land surface temperature (LST) is derived from a thermal band as an alternative meteorological station’s data. In this research, ...

Drought Monitoring Based on the Vegetation Temperature Condition Index by IDL Language Processing Method

WenHao Ou, Wei Su ** , Chen Wu, ZhongZheng Zhu, YanMin Li, Shi Shen (Collage of Information and Electrical Engineering, China Agricultural University, Beijing, 100083) Abstract:Landsat TM5 images are used to calculate and retrieve normalized difference vegetation index (NDVI) and land surface temperature (LST). Combining with two index mentioned, vegetation temperature condition index (VTCI) ca...

On the Role of Land Surface Temperature as Proxy of Soil Moisture Status for Drought Monitoring in Europe

Remotely sensed Land Surface Temperature (LST) represents a valuable source of data for a simple modelling of the dynamic of soil moisture (SM) over large areas. In this paper we evaluated the capability of LST monthly anomalies, derived from the MOD11C3 standard product, to capture the SM dynamic as modelled over Europe by means of an ensemble of three land surface models. The direct use of LS...
