We are happy to introduce a new version of our bulk download service for lightning data. The bulk download service let you download data as .zip files, containing all historical available data, data for a year or a month.

The new version of the bulk download service for lightning data has the same format as the bulk download service for climate data.

The data in the .zip files is identical in old and new bulk download service.

Main differences between the old and the new bulk download service are:

  • Data in the zip files is one file per day instead of one big file. This makes it easier to quickly find data for a range of dates.
  • Year and month files are in a subfolder per year to make it easier to get an overview. This also means that any references to monthly files need to be updated to include year in path. (…/bulk/ -> …/bulk/2022/
  • New .zip file per year
2.3April 6th 2022
Data has been refreshed.The station table has been updated with station history similar to the other APIs. This means that sensor 4 has two station entries - one for the time until May 11th 2007 and one after.
2.2March 22nd 2022
Data has been refreshed.
2.1January 14th 2021

Introduced a limit on the request offset, so no offset can be greater than 1,000,000.

This change prevents the API from returning an error due to connection timeout, and will instead give the user a "400 Bad Request" response.

This change results in the API behaving slightly different, if you query very high offsets.
