Brazilian Atlas of Solar Energy - 2nd Edition (2017)

After more than 10 years of its first edition, the Impacts, Adaptation and Vulnerability Division (DIIAV) of the National Institute for Space Research (INPE), through its Laboratory of Modeling and Studies on Renewable Energy Resources (LABREN), has the satisfaction to publish the second, expanded and revised edition of the Brazilian Atlas of Solar Energy. This is an example of a cooperative work between INPE and researchers from several institutions in Brazil: the Federal University of São Paulo (UNIFESP), the Federal University of Santa Catarina (UFSC), the Federal Technological University of Paraná (UTFPR) and the Federal Institute of Santa Catarina (IFSC).

For this new edition, more than 17 years of satellite data have been used and several advances have been implemented in the parameterizations of the BRASIL-SR radiative transfer model, in order to further improve the reliability and accuracy of the produced database made available for public access. In addition to these advances, the new version contains analyzes about confidence levels, about the spatial and temporal variability of the solar resource, as well as about scenarios for the use of various solar technologies. Although the focus of the Atlas is the energy area, the data presented also serve users in various other areas of knowledge, such as meteorology, climatology, agriculture, hydrology, and architecture.

Database - General Features

The database is available in different ranges: for the ENTIRE BRAZIL, for EACH STATE separately, for the MUNICIPAL HEADQUARTERS and as a CONSULTATION TO SPECIFIC LOCATIONS.

The database is composed of 72272 records containing the annual and monthly averages of the daily total of the Global Horizontal, Diffuse, Direct Normal, Tilted Plane and PAR irradiation in Wh/m

Spatial resolution of 0.1° x 0.1° (approximately 10 km x 10 km).

Longitude and latitude define the centroid of the entities, or cells, of 0.1° x 0.1°.

Character set Unicode UTF-8.

Access to the database through download is available in 3 formats:

CSV (Delimited text)

SHP (Shapefile)

QGS (QGis project)

The CSV format is indicated for reading in spreadsheets such as Microsoft Excel and OpenOffice Calc, for example.
          • The field delimiter is the semicolon (;).
          • The decimal separator is the period (.).

The SHP format is intended for reading on Geographic Information Systems (GIS).

The QGS format is suitable for QGis software users. Contains a working project with the databases of all the irradiations configured with the same color ramp used in the Atlas.


* the metadata file is included in the downloads


Database download or query - BY STATE or MUNICIPALITIES HEADQUARTERS

Here you can:

  • Get the CSV, SHP and QGS formats for each Brazilian state;
  • Obtain the irradiations in the municipalities headquarters and capitals of each state;
  • Find the values of a specific location.
