In this study, the Sea and Land Surface Temperature Radiometer (SLSTR) instrument onboard the Sentinel-3 platform was used to map drought using the Vegetation Temperature Condition Index (VTCI) algorithm based on the scattering space technique of Land Surface Temperature (LST) a...
The map was created using ArcGIS 10.2 (ESRI Inc., Redlands, California, USA). The drought frequencies in the middle and lower reaches of the Yangtze River Plain and the eastern coastal areas were much lower (<20%). There is also clearly difference in mean drought frequency between provinces...
The Standardized Precipitation Index (SPI) was estimated by fitting a gamma distribution to random samples of differing lengths, with each random sample being generated by the observed moving window generative gamma distribution for each site. The absolute SPI error was then computed using the known ...
Then, the drought-pregnant environment and drought-inducing factors were integrated through deep learning to generate the 30 m Environmental Drought-Inducing Index (EDII). Finally, the joint cumulative distribution was used to couple VCAI and EDII, and the 30 m High spatial resolution Drought ...
Here, we used solar-induced chlorophyll fluorescence, water balance, soil moisture, and land surface temperature to develop a new integrated remote sensing drought index, namely interpretable machine learning drought index (IMLDI), based on the Bayesian optimized tree-based Light Gradient Boosting ...
LA QUINTA, Calif. (AP) — A Southern California desert city rejected a proposal for a surf lagoon surrounded by hundreds of homes and hotel rooms after critics argued it's the wrong project in the midst of a punishing Western drought.

2.3. Calculation of the agriculture stress index (ASI) The first step of ASI is to calculate a temporal average of the VHI assessing the intensity and duration of dry periods occurring during the crop cycle at pixel level (temporal aggregation). The second step is the calculation of the perce...
