precip_past10minkg/m²Accumulated precipitation in the latest 10 minutes. kg/m² is equivalent to mm.10 minXX
precip_past1minkg/m²

Accumulated precipitation in the latest minute. kg/m² is equivalent to mm.

Data is sent to from the rain gauge to the DMI every 10 minutes, if it has rained within the 10 minute period. No data is sent, if it hasn't rained within the 10 minute period.

Therefore, data will be null, if it hasn't rained within the 10 minute period. If, however, it has rained within the 10 minute period, the minutes, where it has rained, will show, how much it has rained during each of the minutes in question, whereas the minutes, where it didn't rain will be shown as '0'.

*In Greenland the precipitation is at some locations measured manually once a day. Once a month DMI receives the data, whereafter the data will be available through our API-services.There can be some instances where precipitation has not been measured daily for different reasons. There can therefore be instances, where a measurement can cover the accumulated precipitation of more than a day. A way to detect whether a measurement covers more than one day's accumulated precipitation, if there are not any data for the previous day(s). 

**Some stations in Greenland only send data on an hourly basis.
