TL;DR: In this paper , the authors show that despite an 18.51% increase in leaf area index (LAI) during 2001-2019, this increase failed to translate into increased carbon uptake due to warming constraints.
Remote sensing and climate services improve irrigation water management at farm scale in Western-Central India.
TL;DR: In this article , the authors developed an irrigation water management tool for the farmers at farm scale, which starts with utilizing and merging a few available soil moisture sensors and L-band satellite observations of surface soil moisture using machine learning.

Analyzing spatio-temporal pattern of the forest fire burnt area in uttarakhand using sentinel-2 data
TL;DR: In this article , the spatial and temporal pattern of the burnt area was analyzed by incorporating different parameters such as meteorological parameters like land surface temperature, rainfall, edaphic parameter like surface soil moisture and vegetation parameters like Normalized Difference Vegetation Index and Enhanced Vegetation index.
Impact of forest fire emissions on air quality over western himalaya region
TL;DR: In this paper , the impact of forest fire events on the tropospheric concentrations of five major gaseous pollutants aerosols, Carbon Monoxide (CO), Nitrogen Dioxide (NO2), Sulphur Dioxide(SO2) and Formaldehyde (HCHO) was analyzed.
