TLDR
In this paper, the authors used the two first indices are based on precipitation only, but the RDI uses precipitation and the potential evapotranspiration (PET), but Hargreaves method is more accurate for semi-arid regions.About:

Historical analysis (1981-2017) of drought severity and magnitude over a predominantly arid region of Pakistan
Saadia Hina,Farhan Saleem +1 more
TL;DR: In this paper, the applicability and comparison of three drought indices (deciles index [DI], standardized precipitation index [SPI] and reconnaissance drought index [RDI]) in Pakistan were evaluated.
Journal ArticleDOI
Normalized difference vegetation index as the dominant predicting factor of groundwater recharge in phreatic aquifers: case studies across Iran.
TL;DR: The estimation of long-term groundwater recharge rate (GWr) is a pre-requisite for efficient management of groundwater resources, especially for arid and semi-arid regions, and the effect of eight predicting factors were assessed.

Mediterranean-Scale Drought: Regional Datasets for Exceptional Meteorological Drought Events during 1975-2019
TL;DR: In this article, the authors extracted a dataset of exceptional meteorological drought events between 1975 and 2019 at the country and subregional scales, where each drought event was described by its start and end date, intensity, severity, duration, areal extent, peak month and peak area.

Evaluation of the TRMM Product for Monitoring Drought over Paraíba State, Northeastern Brazil: A Statistical Analysis
Reginaldo Moura Brasil Neto,Celso Augusto Guimarães Santos,Thiago Victor Medeiros do Nascimento,Richarde Marques da Silva,Carlos Antonio Costa dos Santos +4 more
TL;DR: It is concluded that rainfall estimates from the TRMM satellite are a valuable source of data to identify drought behavior in a large part of Paraíba State at different time scales, and further multidisciplinary studies should be conducted to monitor these phenomena more accurately based on satellite data.
Journal ArticleDOI
Simulation of meteorological drought using exponential smoothing models: a study on Bankura District, West Bengal, India
TL;DR: In this article, the authors compared the performance of Holt-Winter exponential smoothing model (HW) and double exponential (DE) for several time steps (e.g., 3 months, 6 months, 12 months, 24 months, and 48 months) in the time period of 1979-2014.

Reference Crop Evapotranspiration from Temperature
TL;DR: In this paper, an equation is presented that estimates ETo from measured values of daily or mean values of maximum and minimum temperature. But this equation is compared with various other methods for estimating ETo.

Journal ArticleDOI
Estimating Potential Evapotranspiration
TL;DR: In this article, four methods for estimating potential evapotranspiration are compared and evaluated: the Class A evaporation pan located in an irrigated pasture area, the Hargreaves equation, the Jensen-Haise eguation, and the Blaney-Criddle method.
