|---|---|---|---|---|---|---|
| 31 | FP exceptions in asad_sparse_vars or asad_spimjmp |
#368 (MOSRS) | Nick Savage | leave open | ||
| 35 | Error in labelling: Surface resistance <--> stomatal resistance ? | MOSRS #1409 | Fiona O'Connor | leave open | ||
| 57 | Incorrect logic for DMS anciliaries required | #756 (MOSRS) | Nick Savage | Possibly close: JM to check impact | ||

#1250 | Alan Hewitt? | leave open | ||
| 74 | Bug in ukca_tropopause with definition of PV tropopause | #1283 | Steven Hardiman | leave ope | ||
| 75 | Bug in STE fluxes | #1367 | Fiona O'Connor | leave open. still not sure what is going on | ||
| 87 | Possible issues with YSTORE in UKCA_CHEMISTRY_CTL. | UM#3245 | Colin Johnson/ Luke Abraham |
leave open | ||
| 92 | UMDP084 incorrectly labels 38-476 ("Liquid cloud fraction") with units "m-3". It is a pure fraction (in the range 0.0 to 1.0) and so has no unit. | |||||
