Conversion doesn't handle duplicate variables correctly #60
Description
When passing several Tair, VPD etc. output variables (e.g. TA_F_MDS and TA_F) at the same time, this causes problems in the unit conversions. Several columns are selected and the original data gets duplicated, ultimately leading to an error elsewhere in the code.
Need to look into this and ideally use the corresponsing variables, e.g. TA_F when converting VPD_F.
