Hi This is more a data gap than a software bug, but it prevents trajectory modelling on the 12th of June 2019. It looks like inadvertent omission, hence I post it as a bug. The gap arises because the GDAS 0.5 global met field set ends on 11 June 2019, while the GFS 0.25 one that replaces it starts o...

Relative humidity values that are output (and plotted) by HYSPLIT are very different, depending on the met data set chosen. E.g. for GDAS 1km the humidity appears to be with respect to ice at lower temperatures. However, for GDAS 0.5km (GFSG) this seems to change to water, although the name of the v...
