To plug gaps successful workplace fires data, authorities agencies, including Indian Agricultural Research Institute (IARI) and National Remote Sensing Centre (NRSC), are moving to make a methodology to fine-tune and standardise mapping of “stubble burnt areas”, The Indian Express has learnt.
Gaps successful workplace fires from Punjab and Haryana, owed to the “undercounting bias” of the polar-orbiting satellites which seizure occurrence events occurring arsenic they are passing implicit the region, were precocious brought to the announcement of the Supreme Court. The tribunal directed the Centre and the Commission for Air Quality Management successful the National Capital Region and Adjoining Areas to procure information besides from geostationary satellites too NASA’s polar-orbiting satellites.
The NRSC, Indian Council of Agricultural Research (ICAR)-IARI and distant sensing centres of Punjab and Haryana are carrying retired an in-season aviator to steadfast up the methodology this Kharif season. The agencies are utilizing European Sentinel-2 outer for this, which has a 20-metre solution and passes each 5th day. They supply optical images, near-infrared images and short-wave infrared 1 and short-wave infrared 2 images, helping successful mapping pain scars connected fields.
The agencies progressive had been mapping burnt areas earlier too, albeit independently.
CAQM initiated a treatment connected gaps successful workplace fires number successful January. It formed a committee nether NRSC to standardise a protocol for mapping areas burnt by paddy stubble fire.
“Thermal imaging satellites, adjacent with a finer resolution, cannot way each and each occurrence incident. They volition seizure those occurrence events that are occurring arsenic they (satellites) are passing over, truthful determination is ever an undercounting bias,” said a scientist.
ICAR-IARI, NRSC and the authorities distant sensing centres usage information collected by Suomi NPP, Terra MODIS and Aqua MODIS satellites. The in-season aviator has been checking real-time what are the impediments faced portion mapping burnt areas. For instance, smog tin pb to poorer detection and solutions are being tested. On the contented of undercounting, the idiosyncratic said, “We are alert of this contented and hence we person been moving unneurotic to fine-tune occurrence detection.”
On Monday, it was pointed retired to the Supreme Court that determination could beryllium an undercount successful the information connected workplace fires collected done the polar-orbiting NASA satellite. Farm occurrence events successful Punjab person dropped from 82,147 successful 2020 to 10,104 till November 20 this year; successful Haryana the number has dropped from 6,464 to 1,183 successful the aforesaid period, according to information from IARI.
Relying connected X posts of a NASA scientist, Hiren Jethva, it was pointed to the apex tribunal that information from the geostationary GEO-KOMPSAT 2A, a Korean satellite, had picked up fires aft NASA’s polar-orbiting had passed over, raising questions implicit the number of workplace fires. The Supreme Court past directed the CAQM to get information from the Korean outer oregon immoderate different outer to alteration enactment astatine the authorities level.
On geostationary satellites, a idiosyncratic said, “The disposable geostationary thermal sensors are not suitable for workplace occurrence detection arsenic the sensors person coarse solution and person debased sensitivity to tiny fires.”
