Syllabus: GS-III
Subject: Science & Technology
Topic: Developments and their Applications in Everyday Life
Context: India Meteorological Department (IMD) report of a high likelihood of “very dense fog” in Haryana, Chandigarh, and Delhi.
Synopsis:
- IMD has used maps from the INSAT 3D and INSAT 3DR satellites.
- Both satellites use radiometers to make their spectral measurements.
- A radiometer is a device that measures various useful properties of radiation like temperature and electrical activity.
- The INSAT (Indian National Satellite System)
- series of multipurpose geostationary satellites launched by ISRO
- For weather monitoring, forecasting and warning services (meteorology), telecommunications, broadcasting, and search and rescue operations.
- Kalpana-1 is an exclusive meteorological satellite launched by PSLV in September 2002. Deactivated Kalpana 1 in 2017.
Conclusion: ISRO is expected to launch the INSAT 3DS meteorological satellite in 2024 which will further improve the weather forecasting and warning capabilties in India.
