I left last night before things really started getting going for the dry run.  From co2 data, it seems like conditions were good for the first ~2 hours, and CTEMPS was running (for the bit of it that was deployed).  April still doesn't have the Doppler lidar, but they were going to try smoke and 2 aerosol lidars.  Kate reports that the one radiosonde worked, but had a very low rise rate – they cut it off after 45min to 700mb.
