Accumulations are described in section ERA5-Land data documentation. The accumulations in monthly means (stream=moda/mnth) are described in section monthly means

- Possible issue: There is a positive bias in ERA5 snow cover. This is even after the assimilation of snow reports. The IMS snow cover product is not assimilated over mountainous areas in ERA5, which probably is part of the issue. In ERA5-Land no data is directly assimilated, which makes the positive bias more prominent, especially in areas of high-elevation.
- Possible issue: Possible shift one skin temperature due to long time step of 1 hour. (TO BE UPDATED BEFORE MAKING IT PUBLIC **********)
