Atmosphere & Climate Research-Modelling Observing Systems & Services (ACROSS) Scheme

Context:  Recently, the Minister of Earth Sciences provided information on the ACROSS scheme in Lok Sabha. About ACROSS Scheme:
  • It is a central sector scheme under the Ministry of Earth Sciences (MoES) for atmospheric science programs.
    • Aims: To address various aspects related to weather and climate prediction through a comprehensive approach.
  • Sub-Schemes:
    • Each of these aspects is incorporated as eight sub-schemes under the umbrella scheme “ACROSS”.
    • Each sub-scheme focuses on a specific aspect of atmospheric science and is implemented by different institutions under MoES.
  • Implementing Institutions:
    • India Meteorological Department (IMD)
    • National Centre for Medium Range Weather Forecasting (NCMRWF)
    • Indian Institute of Tropical Meteorology (IITM)
    • Indian National Centre for Ocean Information Services (INCOIS)
  • Benefits:
    • Improved accuracy and reliability of weather and climate forecasts.
    • Enhanced disaster preparedness and response capabilities.
    • Facilitation of sustainable development through better climate information.
    • Beneficial for various sectors, including agriculture, transportation, and disaster management.
