AI-powered climate models are highly effective in forecasting complex phenomena like extreme weather events (e.g., heatwaves, floods, droughts), assessing their impact on agricultural yields, and aiding in better water resource management, which are critical challenges for India.

Machine Learning (ML) is the predominant branch of AI used in climate modeling. It enables models to learn from historical and real-time climate data, recognize intricate patterns, and make more accurate predictions about future climate conditions and extreme weather events.

AI-powered climate models, including those developed by Indian researchers, excel at processing vast datasets and identifying complex patterns, leading to significantly faster and more accurate climate predictions and simulations compared to traditional models.

Ka-band is increasingly used by advanced high-throughput communication satellites for high-speed data transmission, enabling services like broadband internet and DTH television due to its higher bandwidth capacity compared to C-band or Ku-band.

The Geosynchronous Satellite Launch Vehicle Mark-III (GSLV Mk-III), now known as LVM3, is ISRO's heaviest operational launch vehicle, specifically designed for launching 4-ton class communication satellites into Geostationary Transfer Orbit (GTO).

Advanced communication satellites like GSAT-N2 (formerly GSAT-20) are high-throughput satellites (HTS) designed to provide high-speed broadband internet connectivity, especially to remote and underserved areas, thereby boosting India's digital infrastructure.
