# 2025 model release notes

| Release date | Release |
| --- | --- |
| 30.10.2025 | - **Introduced new hail parameters** (`HAILRISK25MM`, `HAILRISK38MM`, `HAILRISK50MM`) based on the HRRR model available for continental US (Alaska excluded) |
| 8.7.2025 v 2.2.64 | - **Improved calculation of interannual variability** incorporated in TMY Pxx scenario generation. |
| 16.6.2025 v 2.2.63 | - **Integrated CAMS EAC4 reanalysis for particulate matter (PM) data** for the year 2024, providing improved temporal consistency of PM parameters. - **Enhanced TMY processing** to ensure consistency of data across temporal resolutions (1, 5, 10, 15, and 60 minutes). |
| 21.3.2025 v 2.2.62 | - Resolved an issue in Solargis Forecast & Monitor API where results were reported with excessive decimal places; parameter-specific rounding rules are now applied. - Updated **physical limits for GHI values used in SYNGENA 1-minute data simulations**, ensuring data remains within consistent physical ranges. |
| 11.2.2025 v 2.2.61 | - Enhanced **push delivery data format** for forecasts to improve consistency and usability. - Modified **rounding methodology for calculating Pxx yearly values** in TMY generation. |
| 16.1.2025 v 2.2.60 | **Enhanced Data Integration:** - **PREC from ERA5-Land**: The `PREC`(Precipitation) data from the ERA5-Land model, which operates at a resolution of approximately 12 km, has been integrated into our system. - **Ocean and Sea Surface Data**: For ocean and sea surface areas, ERA5 data is utilized to ensure comprehensive coverage and accuracy. - **IRRAD file Format Update**: The monthly files for 2024 from the sat model have been replaced with read-optimized yearly files, enhancing data access efficiency. |
