API for meteorological observation data. DMI performs a wide array of point measurements at its observing stations in Denmark, Greenland and Faroe Islands. This is an automated process in which wind, precipitation, temperature, humidity, visibility, pressure, cloud cover, weather and global radiation are measured, and data is transmitted to DMI. Meteorological observation data are so-called raw data, which means that data is neither quality controlled nor processed in any way.

Sea Ice Frequency charts display the percentage of days with more than 15 % ice coverage for each month over a 30 years periode.
