Modeling reference evapotranspiration using machine learning and remote sensing techniques for semi-arid subtropical climate of Indian Punjab

open access: yesJournal of Water and Climate Change, 2023
A study was carried out to develop and evaluate the performance of different machine learning (ML) models for predicting reference evapotranspiration (ET0). The models included multiple linear regression (MLR), least square-support vector machine (LS-SVM)

An algorithm for retrieving aerosol optical depth from Landsat 8 Operational Land Imager in Vietnam

open access: yesGeocarto International, 2023
High-resolution aerosol products offer advantages over lower spatial-resolution products for monitoring pollution in urban areas and industrial zones. Therefore, in this study we develop a Landsat 8 algorithm to retrieve aerosol optical depth (AOD) based

Evaluation of MODIS LAI/FPAR product Collection 6. Part 2: Validation and intercomparison [PDF]

open access: yes, 2016
The aim of this paper is to assess the latest version of the MODIS LAI/FPAR product (MOD15A2H), namely Collection 6 (C6). We comprehensively evaluate this product through three approaches: validation with field measurements, intercomparison with other ...

Synthesis of satellite (MODIS), aircraft (ICARTT), and surface (IMPROVE, EPA-AQS, AERONET) aerosol observations over eastern North America to improve MODIS aerosol retrievals and constrain surface aerosol concentrations and sources [PDF]

open access: yes, 2010
We use an ensemble of satellite (MODIS), aircraft, and ground-based aerosol observations during the ICARTT field campaign over eastern North America in summer 2004 to (1) examine the consistency between different aerosol measurements, (2) evaluate a new ...

Variations of LST frequency Distribution as an Indicator of Environmental Changes, Case Study Zayabderood and Urmia basins [PDF]

open access: yesمخاطرات محیط طبیعی, 2019
Anthropogenic environmental changes can have serious consequences. Environmental changes affect the frequency distribution of the land surface temperature (LST) due to changes in the thermal properties of the land surface.
