MUMBAI, India, July 11 -- Intellectual Property India has published a patent application (202521059827 A) filed by Dr. Lata K Kamthekar; and Mr. Gangadhar P. Nivdange, Nashik, Maharashtra, on June 23, for 'a climate projection and downscaling system and a method for downscaling and forecasting climate-driven hydrological parameters.'
Inventor(s) include Dr. Lata K Kamthekar; and Mr. Gangadhar P. Nivdange.
The application for the patent was published on July 11, under issue no. 28/2025.
According to the abstract released by the Intellectual Property India: "The present invention relates to a climate projection and downscaling system (100) for hydrological prediction and trend analysis, comprising: i) a data acquisition module (101) configured to collect and store historical observed station-level data and CMIP-based General Circulation Model (GCM) data; ii) a re-gridding unit (102) adapted to interpolate GCM gridded data to station-scale resolution using bicubic spline interpolation; iii) a missing data imputation module (103) configured to perform temporal interpolation of station datasets using said bicubic spline method; iv) a statistical normalization module (104) configured to preprocess the datasets into daily time-series for analysis; v) a feature selection unit (105) incorporating entropy gain (EG), gain ratio (GR), and symmetrical uncertainty (SU) for identifying optimal GCM predictors; vi) a trend analysis module (106) configured to assess monotonic trends using Mann-Kendall (MK) trend testing; vii) a machine learning engine (107) comprising an Extreme Gradient Boosting (XGBoost) algorithm, trained using calibrated datasets for local statistical downscaling; ix) a climate change projection unit (108) configured to apply additive and multiplicative change factors to simulate future climate scenarios; and x) an output interface (109) adapted to display future hydrological outputs for user-defined river basins and seasonal slices."
