SHIMLA: To study the impact of global warming on melting of glaciers and environment in general, the Indian Space Research Organisation (Isro) has decided to set up an observatory at Kothi near the 13,050-feet-high Rohtang Pass.

Scientists would be studying the behavior of aerosols, glaciers and back carbon aerosols at the poplar mountain tourist spot. With thousands of vehicles passing through Rohtang, especially during peak tourist season, on a daily basis, the white snow cover turns black due to carbon emission from vehicles. Increased quantity of black carbon aerosols in the atmosphere is absorbing more heat, due to which incoming solar radiation is being absorbed more and not reflected accordingly, resulting into faster melting of glaciers.

J C Kuniyal, senior scientist at G B Pant Institute of Himalayan Environment and Development, Mohal, who is associated with the project, said that setting up of an observatory would help in collecting data that would be helpful for the preservation of glaciers and to know the rise in temperature due to global warming.

Kuniyal said with the setting up of an observatory at Kothing or Gulaba near Rohtang, study would be done to know how fast the glaciers were melting. He said data collected would also be used to study presence of aerosols in the atmosphere and its relative impact on the environment. He added that villagers would be approached to get the required land to set up the observatory in open space as the project would be carried on for a minimum three-year period.

Apart from setting up an Isro observatory, a weather tower would also be set up at Kothi or Gulaba village to have better weather forecasting and to study the presence of aerosols in atmosphere in connection with climate change. Earlier plans to have a tower near Rohtang failed as villagers had refused to part with their land, after which weather tower was set up at Mohal.

Now another tower would be set up near Rohtang under a Union government project to set up weather towers in the Himalayan region of Arunachal Pradesh, Himachal Pradesh, Jammu & Kashmir and Uttarakhand. As these towers would get energy from solar panels, and collection of data from inaccessible areas would become much easier.

Kuniyal said data collected from the centre would also help the Union government frame environment policies accordingly, besides helping local people and other stakeholders including defence personnel.
