v2 | August 30th 2022 |
We are happy to introduce a new version of our bulk download service for meteorological observation, oceanographic observation and 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 meteorological observation, oceanographic observation and 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:
|
||
| Climate Data | v2 | June 28th 2022 | Data with parameterId corrected_acc_precip has been removed from the dataset. This parameter is a special product and is therefore not part of DMI Open Data. Access can be purchased through customer support. | For stationValues there are no longer invalid values with 'max_precip_30m' in the dataset. | |
| Forecast Data | v1 | October 25th 2022 |
New forecast model HARMONIE is now available in the API - details can be found here. Currently the process for getting data to the API is only monitored during office hours so lack or delay of data can occur outside office hours. We are in progress of promoting this to the usual 24/7 setup. |
||
| Forecast Data | v1 | June 14th 2022 |
New forecast model DKSS (Storm Surge) is now available in the API - details can be found here. Currently the process for getting data to the API is only monitored during office hours so lack or delay of data can occur outside office hours. We are in progress of promoting this to the usual 24/7 setup. |
||
| Forecast Data | v1 | April 26th 2022 |
First version of the forecast service. This release contains WAM model data - details can be found here and has the last two days of generated forecast models. Currently the process for getting data to the API is only monitored during office hours so lack or delay of data can occur outside office hours. We are in progress of promoting this to the usual 24/7 setup. |
||
| Oceanographic Observation Data | v2 | April 19th 2022 |
Oceanographic data refreshed with more stations: 23131, Juelsminde Havn II |
||
| Lightning Data | v2 | April 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. | |
| Meteorological Observation Data | v2 | March 15th 2022 | Maximum offset has been decreased to 500.000 due to poor performance with larger values. See offset documentation | ||

Station 06184 Danmarks Meteorologiske Inst. has been removed. |
||
| Radar Data | v1 | January 27th 2022 |
Volume and composite files have a new property which is also queryable: scan type. The scan type of a radar image is either full range or doppler, and tells you the scanning range of the radars in the image. For full range images the radar range has a radius of 240 km, while for doppler it is 120 km. For additional details, see link. For more on how to query the API for scan type, please see either "Service documentation -> OpenAPI specification" or "Service documentation -> Request & Response Examples". |
||
| Radar Data | v1 | December 14th 2021 |
The radardata service is released with 180 days of historic radar data. There are are a few radar data files missing - we are working on patching these with archived data where possible. As mentioned here half of the volume and composite images have smaller size due to doppler scan. We are working on showing this in the Features properties and adding the ability to filter on radar range in the API endpoints. Please note, that our radar data files to some extent differs from the ODIM HDF5 standard in relation to metadata. DMI is in 2022 planning on using a newer version of ODIM HDF5 standard, where the issue in relation to metadata will be fixed. At this time the service does not have an API-endpoint for the stations. Information about the radar stations can be found here. |

Please note that the bulk download feature for climateData is not part of this release. It will be released as soon as possible. Please also note that it is not possible to filter by 'qcStatus' and 'validity'. This will be possible in a future release.
Known issues in this release:
|
||
| Oceanographic Observation Data | v2 | January 19th 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. |
