Release notes

Recent updates of Solargis database and online applications

10 Nov 2016

New updates in iMaps and pvPlanner data

Data periods for Eastern Asia, Australia and New Zealand have been extended; with this update, the model used for iMaps and pvPlanner now represents data up to 2015 for all the regions. More updates will follow as soon as new complete years are available.

In addition, the use of daily aerosol data in iMaps and pvPlanner is now implemented for Americas, Hawaii and Western Pacific. The calculation of the optimum angle for Europe, Africa, Middle East and Central Asia has been also improved.

Regular data delivery on daily basis available for New Zealand

Updates of Solargis recent data can be now delivered on a daily basis for any location in New Zealand. For this region, input data for Solargis cloud modelling is obtained from Himawari satellite and allows an original time granularity of 10 minutes.

Extended geographical and temporal coverage in pvPlanner and iMaps database

Solargis pre-calculated weather database connected to the online applications iMaps and pvPlanner has been updated.

Data periods used for the calculation of the averaged values provided include now latest complete years (up to 2015) for Europe, Africa and Asia regions. In terms of geographical coverage, iMaps and pvPlanner are now available for whole territories of Russia (up to paralell 60ºN), Kazakhstan and Mongolia.

Latest versions of the algorithms for solar radiation and temperature have been also implemented.

Full temporal coverage of daily input data for characterization of aerosols

Additional inputs from MERRA-2 (NASA) have been included for describing Atmospheric Optical Depth (AOD) in our solar radiation model.

This allows the generation of harmonized daily aerosol time series used in Solargis algorithms.

Enhanced spatial resolution in aerosol input data

The spatial resolution of aerosol data used in Solargis algorithms has been improved. From periods since June 2016 onwards, the resolution of Atmospheric Optical Depth (AOD) input data from MACC/CAMS models is now 0.4x0.4 deg. (approx. 45x45 km at the equator).

This release represents a step ahead of previous models. For data periods from October 2015 up to June 2016, 0.75x0.75 deg. resolution is available (approx. 85x85 km at the equator); for data periods before October 2015, 1.125x1.125 deg. resolution is available (approx. 125x125 km at the equator).

New Himawari satellite brings improvements to Solargis in Pacific region

We have released SolarGIS model from Himawari 8 satellite data. A new generation Himawari 8 satellite, operated by Japan Meteorological Agency from January 2016, replaces older MTSAT satellite (decommissioned in late March 2016). The satellite is positioned approximatelly on the 140.7°E longitude, covering the Pacific region (countries like Japan, eastern parts of China, Malaysia, Indonesia, Philippines, Australia and other Pacific countries and islands).

Thanks to new generation satellite data we implemented improvements in our modelled solar resource data:

  • 10-minute time-step
  • more spectral channels employed in the identification of the clouds and snow detection
  • two times higher spatial resolution and image quality
  • short data retrieval delay allow nowcasting of solar resource and PV electricity generation

Presently, new data can be purchased as recent time-series from climData application.
