Inconsistencies of interannual variability and trends in long-term satellite leaf area index products [PDF]

open access: yes, 2017
Understanding the long-term performance of global satellite leaf area index (LAI) products is important for global change research. However, few effort has been devoted to evaluating the long-term time-series consistencies of LAI products.

Modification and validation of a new method to improve the accuracy of MODIS-derived dew point temperature over mainland China

open access: yesInternational Journal of Digital Earth, 2023
MODIS atmospheric profile products (MOD07_L2 and MYD07_L2) have been widely used for near-surface dew point temperature ($T_d$) estimation. However, their accuracy over large scale has seldom been evaluated. In this study, we validated these two products

A multi-sensor data-driven methodology for all-sky passive microwave inundation retrieval [PDF]

open access: yes, 2017
We present a multi-sensor Bayesian passive microwave retrieval algorithm for flood inundation mapping at high spatial and temporal resolutions. The algorithm takes advantage of observations from multiple sensors in optical, short-infrared, and microwave ...

Downscaling MODIS spectral bands using deep learning

open access: yesGIScience & Remote Sensing, 2021
MODIS sensors are widely used in a broad range of environmental studies, many of which involve joint analysis of multiple MODIS spectral bands acquired at disparate spatial resolutions.

Process-Oriented Estimation of Chlorophyll-a Vertical Profile in the Mediterranean Sea Using MODIS and Oceanographic Float Products

open access: yesFrontiers in Marine Science, 2022
Reconstructing chlorophyll-a (Chl-a) vertical profile is a promising approach for investigating the internal structure of marine ecosystem. Given that the process of profile classification in current process-oriented profile inversion methods are either ...

Multiscale assimilation of Advanced Microwave Scanning Radiometer-EOS snow water equivalent and Moderate Resolution Imaging Spectroradiometer snow cover fraction observations in northern Colorado [PDF]

open access: yes, 2012
Eight years (2002–2010) of Advanced Microwave Scanning Radiometer–EOS (AMSR-E) snow water equivalent (SWE) retrievals and Moderate Resolution Imaging Spectroradiometer (MODIS) snow cover fraction (SCF) observations are assimilated separately or jointly ...

Upscaling key ecosystem functions across the conterminous United States by a water-centric ecosystem model [PDF]

open access: yes, 2011
We developed a water-centric monthly scale simulation model (WaSSI-C) by integrating empirical water and carbon flux measurements from the FLUXNET network and an existing water supply and demand accounting model (WaSSI).

Upscaling fluxes from towers to regions, continents and global scales using datadriven approaches [PDF]

open access: yes, 2011
Quantifying the current carbon cycle of terrestrial ecosystems requires that we translate spatially sparse measurements into consistent, gridded flux estimates at the regional scale.
