The unit of total precipitation in the ERA-Interim (Jan 1979 - present) database is meter. Here it is said to be kilogram per square meter. Is this intended? And if so, what is the reason?

The TIGGE is a newer archive in GRIB2 format where the intention is to use only WMO compliant (GRIB2) definitions. For total precip it is kg m-2
We have the same approach for all new public datasets (TIGGE-LAM, S2S, UERRA etc.). The ERA datasets are older and in GRIB1 with units used by IFS (or agreed at the beginning of the archiving).
Sorry for that inconvenience.

Where can I find description for other variables like "Large-scale precipitation"(lsp) or "Surface sensible heat flux"(sshf) ,which I can download from ERA-Interim (Jan 1979 - present) ?
