Recent global and regional trends in burned area and their compensating environmental controls [PDF]

, 2019
The apparent decline in the global incidence of fire between 1996 and 2015, as measured by satellite- observations of burned area, has been related to socioeconomic and land use changes.

A Method to Weaken Cloud Interference in Solar-Induced Chlorophyll Fluorescence (SIF) Reconstruction by Using Satellite VOD Observations

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Solar-induced chlorophyll fluorescence (SIF) satellite observations enable large-scale crop monitoring and yield assessment. Some optical vegetation indexes have been commonly used as predictors to reconstruct SIF.

The dry season intensity as a key driver of NPP trends [PDF]

, 2016
We analyze the impacts of changing dry season length and intensity on vegetation productivity and biomass. Our results show a wetness asymmetry in dry ecosystems, with dry seasons becoming drier and wet seasons becoming wetter, likely caused by climate ...

Sensitivity of evapotranspiration components in remote sensing-based models [PDF]

, 2018
Accurately estimating evapotranspiration (ET) at large spatial scales is essential to our understanding of land-atmosphere coupling and the surface balance of water and energy.

Sentinel-1 vegetation optical depth retrievals over the international soil moisture network

International Journal of Digital Earth
Vegetation optical depth (VOD), a microwave-based vegetation index for vegetation water content and biomass, is primarily retrieved from low spatial resolution passive microwave data, and few studies have focused on VOD retrievals from active microwave ...

A global daily seamless 9-km Vegetation Optical Depth (VOD) product from 2010 to 2021

Earth System Science Data
Abstract. Vegetation optical depth (VOD) products provide information on vegetation water content and correlate with vegetation growth status, which are closely related to the global water and carbon cycles. The L-band signal penetrates deeper into the vegetation canopy than the higher frequency bands used for many previous VOD retrievals.

Assessing the relationship between microwave vegetation optical depth and gross primary production [PDF]

, 2018
At the global scale, the uptake of atmospheric carbon dioxide by terrestrial ecosystems through photosynthesis is commonly estimated through vegetation indices or biophysical properties derived from optical remote sensing data.

The future of Earth observation in hydrology [PDF]

, 2017
In just the past 5 years, the field of Earth observation has progressed beyond the offerings of conventional space-agency-based platforms to include a plethora of sensing opportunities afforded by CubeSats, unmanned aerial vehicles (UAVs), and smartphone

Uncovering the Key Factors Influencing Phytochemical and Phytopharmacological Properties During Medicinal Plant Processing

eFood, Volume 7, Issue 1, February 2026.
From farm to pharma, this review details the engineering of quality in medicinal plants through a science‐driven approach: it first elucidates how genetic and environmental factors inscribe the plant's phytochemical and phytopharmacological profile before harvest, and then dissects the postharvest techniques and technologies—chemical and thermal pre ...
