Climatic moisture conditions in the north-west of the Mid-Russian Upland during the Holocene

open access: yesGeography, Environment, Sustainability, 2019
This study aimed to reconstruct the climatic moisture conditions of the Mid- Russian Upland through the Holocene. Surface moisture conditions in the study region were inferred from published pollen records from the Klukva peatland, in the north-west of ...

Estimation of weekly potential evapotranspiration

open access: yesMAUSAM, 1984
Weekly potel1tial evapotranspiration is estimated by four different methods- (A) Interpolation of monthly values estimated by modified Penman formula, (B) Estimation by modified Penman formula with weekly meteorological normals and measured net solar radiation as input data, (C) Computed following the method given by Doorenbos and Pruitt (1975) and (D)

Rainfall and potential evapotranspiration patterns and their effects on climatic water balance in the Western Lithoral Hydrological Zone of Nigeria

open access: yesRuhuna Journal of Science, 2018
This study examined the climatic water balance and aridity in the Western Lithoral hydrological zone of Nigeria. Monthly climatic data from 1976-2015 collected from six Nigeria Metrological Agency (NIMET) stations located in Ikeja, Ibadan, Akure ...

Estimation of Potential and Actual Evapotranspiration

open access: yesHydrology Research, 1984
A model for determining the potential and actual evapotranspiration from agricultural crops is presented. The model requires only a limited number of meteorological variables, i.e. global radiation, air temperature and precipitation. The vegetation is characterized by the crop surface area and the efficient root depth.

Green roof seasonal variation: comparison of the hydrologic behavior of a thick and a thin extensive system in New York City

open access: yesEnvironmental Research Letters, 2016
Green roofs have been utilized for urban stormwater management due to their ability to capture rainwater locally. Studies of the most common type, extensive green roofs, have demonstrated that green roofs can retain significant amounts of stormwater, but

The actual evapotranspiration as a function of the potential evapotranspiration and the soil moisture tension.

open access: yesNetherlands Journal of Agricultural Science, 1956
Lysimeter observations with a clay and a peat soil indicated that the actual evapotranspiration of grassland falls below the potential evapotranspiration while the soil is still drying, the fall being less for peat than for clay. The rate of reduction depends on the moisture tension of the soil and on the intensity of the potential evapotranspiration ...

A substantial rise in the area and population affected by dryness in South Asia under 1.5 °C, 2.0 °C and 2.5 °C warmer worlds

open access: yesEnvironmental Research Letters, 2019
Millions of people in South Asia face water scarcity every year. Previous studies based on the multi-model ensemble mean reported a decline in dryness (the ratio of potential evapotranspiration and precipitation) in South Asia under the warming climate ...

Estimation of potential evapotranspiration and its variability in the upper and middle reaches of the Heihe River basin

open access: yesShui kexue jinzhan, 2015
On the basis of the MODIS LAI remote sensing products,China Meteorological Forcing Dataset and other multi-source datasets,the Shuttleworth-Wallace (S-W) model,which considers the temporal variation of leaf area index (LAI),was applied to estimate ...

Modeling and prediction of high-precision global evapotranspiration: based on a different model of physical relationships

open access: yesJournal of Water and Climate Change
The interchange of water vapor between the land and the atmosphere is influenced by actual evapotranspiration (AET). A nonlinear model (AET-SWC-PET-GPP, ASPG) was developed in this study to combine potential evapotranspiration (PET), soil water content ...
