Atmospheric Science & Metrology

The Atmospheric Sciences & Metrology group (formerly known as Radio & Atmospheric Sciences Division) of CSIR-NPL has glorious history and initiated or participated in various national and international scientific programs like International Geophysical Year (IGY), 1957-1958; International Quiet Sun Year (IQSY), 1964-1965; Indian Middle Atmospheric Program (IMAP) during 1980s; Indian Scientific Expeditions to Antarctica; National Methane (CH4) Campaign, INDOEX Program; Free Air Carbon Dioxide Enrichment (FACE) program; Climate And Weather of Sun Earth System (CAWSES) program; Intergovernmental Panel on Climate Change (IPCC) and International Global Atmospheric Chemistry (IGAC) Project and many more.

At present, the group is focused on the following research areas to cater to the national needs:

1. Dynamics of the Earth and planetary atmosphere

  • Lower atmosphere
  • Upper atmosphere: Characterization of the ionized and non-ionized atmospheric media
  • Space environment

2. Pollution: monitoring and its impact assessment

  • Investigation of physico-chemical properties of pollutants
  • Development of emission factors and inventories of greenhouse gases & other pollutants
  • Base line measurements of air pollutants and greenhouse gases
  • Climate change studies

3. Technology development for atmospheric measurement

  1. Certification activity: CSIR-NPL India Certification Scheme (NPLI CS) [View]
  2. Testing & Calibration: Calibration of Ozone Analyzers using Primary Ozone Reference Standard [View]
  3. Capacity building on best practices for accurate atmospheric measurements
  4. Regional Warning Center of India for Space Environment (RWC, NPL-India): Providing geophysical parameters and ionospheric forecasting [View]
