First operational BRDF, albedo nadir reflectance products from MODIS
With the launch of NASA’s Terra satellite and the MODerate Resolution Imaging Spectroradiometer (MODIS), operational Bidirectional Reflectance Distribution Function (BRDF) and albedo products are now… Expand

Abstract Land surface broadband albedo is a critical variable for many scientific applications. High-resolution narrowband satellite observations contain important information that enables us to map… Expand
Narrowband to broadband conversions of land surface albedo: II
Abstract In the first paper of this series, we developed narrowband to broadband albedo conversion formulae for a series of sensors. These formulae were determined based on extensive radiative… Expand
Accuracy assessment of the MODIS 16-day albedo product for snow: comparisons with Greenland in situ measurements
Abstract The accuracy of the Moderate Resolution Imaging Spectroradiometer (MODIS) 16-day albedo product (MOD43) is assessed using ground-based albedo observations from automatic weather stations… Expand
An Improved Land Surface Emissivity Parameter for Land Surface Models Using Global Remote Sensing Observations
Abstract Because land surface emissivity (e) has not been reliably measured, global climate model (GCM) land surface schemes conventionally set this parameter as simply constant, for example, 1 as in… Expand
Use of General Regression Neural Networks for Generating the GLASS Leaf Area Index Product From Time-Series MODIS Surface Reflectance
TLDR
A method was developed to estimate LAI from time-series remote sensing data using general regression neural networks (GRNNs) and it was demonstrated that the method is able to estimate temporally continuous LAI profiles with much improved accuracy compared with that of the current MODIS and CYCLOPES LAI products.

Validating MODIS land surface reflectance and albedo products: methods and preliminary results
Abstract This paper presents the general methods and some preliminary results of validating Moderate-Resolution Imaging Spectroradiometer (MODIS) land surface reflectance and albedo products using… Expand
Validating MODIS land surface temperature products using long-term nighttime ground measurements
Abstract The Moderate Resolution Imaging Spectroradiometer (MODIS), onboard the NASA Terra and Aqua Earth Observing System satellites, provides multiple land surface temperature (LST) products on a… Expand

Fractal analysis of remotely sensed images: A review of methods and applications
TLDR
A survey of several commonly used methods for estimating the fractal dimension and their applications to remote sensing problems and methodological issues related to the use of these methods are summarized. Expand
