New Delhi has experienced severe drop in air quality in the first week of November 2023. The air was said to be ‘unbreathable’. Air Quality is defined as the combined pollution in the ambient atmosphere in the form of solid particles and chemical pollutants. It has been observed that AOD values increased between 2 - 2.5 times, NO2 concentrations by about 2 times and CO concentrations by more than 2 times using MODIS and Sentinel 5P data. EOS-06 images depict transit of a smoke plume over the Punjab, Haryana and Delhi regions. These data indicate that a combination of these events have resulted into a smogy environment. Read More..

Estimation of CO2 fluxes in the shaded coffee ecosystem region of Karnataka
Collaboration with Central Coffee Research Institute for the Carbon Flux Studies with Eddy Covariance in the shaded coffee ecosystem region of Karnataka

Monitoring and assessment of Air Pollution (MAAP) using IOT sensors
A prototype solution to monitor the air quality on CO, PM2.5 and PM10 using cost effective IoT sensors is developed and demonstrated at “Smart City Hackathon 2018"

Continuous CO2 flux information to study the carbon net-energy in the temperate ecosystem is being generated using an eddy covariance flux tower.
