Release Notes

Solar data and PV OUT for North America will be extended up to 65˚N. In the northeastern part data is available from 2018 and in the northwestern part data is available from 2019.

For land areas, higher resolution data from ERA5-Land is implemented. Precipitation (PREC) and snow (SNOWD) datasets will be even more accurate.

• We have changed the CSV file header to simplify the metadata.

• Nowcast history is now available for 2021 and beyond for all regions.
• We have fixed issues with the DIF for extreme conditions at very high altitudes.
• Improved calculation of uncertainty at date transitions (in UTC+0), where discontinuities were identified.

• We have integrated the sun position (PSA algorithm with new parametrization) into the data delivery processing.
• We have fixed instability issues  of GHI and DNI that were caused by extreme aerosols in satellite model.
• We have included PM2.5 and PM10 data for the MERRA2 period (before 2003) in manual data delivery templates.

• We have fixed a bug in reading the 1 km elevation used for height correction of AP and TEMP, which had caused a 1-pixel shift.

• The data delivery core now supports sub-hourly time zones, e.g., UTC+5:30 (+5.5). This functionality is now available across different delivery channels.

Solargis has developed a blended dataset by combining ERA5-Land with ERA5 to improve the accuracy of temperature data.

The new dataset exhibits smoother daily temperature profiles and helps mitigate the issue of missing coastal data by effectively filling the gaps in coastal pixels.

The blended version is accessible in long-term averages (Solargis Prospect), TMY, and time-series data (Solargis Evaluate).

More information about this update is in this blog article.

PREC, WS, DNI, ALB parameters are now available in the LTA API. The list of all available parameters includes GHI, DIF, TEMP, RH, PWAT, DNI, ALB, WS, PREC, PR, GTI, PVOUT. 

Solargis Prospect update: data for Scandinavia, model improvements, new precipitation data source.
