The Ministry of Earth Science has been providing weather / climate related forecasts on land and oceans through its constituent units namely the National Centre for Ocean Range Weather Forecasting (NCMRWF) and the Indian National Centre for Ocean Information Services (INCOIS). This study aims to estimate the cost incurred in producing user-wise customized forecasts of NCMRWF and INCOIS by carefully analysing the economic values/costs and financial costs of the output. The study will also estimate the direct and indirect value of weather services.
