Summary: Shutdown and removed HMP inter-comparison, copies TA AirT/RH data into TA_met_20180111

Twitchell Alfalfa
2017-12-19

I arrived about 12:30. It was cool with a thin overcast and a breeze from the southwest.

The HMP comparison was still running strong. I checked the data and then shut it down. I tried to be careful taking it down to make sure all the important information about its configuration was written down.

I cleaned some spiders and webs out of the TA HMP60 shield before restoring it to its normal location and rewiring it to the CR1000 met data logger.

I returned the other HMPs and their shields to their respective sites and locations.

Note 2019-03-22 by Daphne Szutu:
I updated TA_met_20180111.dat (J:\FieldData\TwitchellAlfalfa\TA_2018\TA_met_2018) with Air T and RH data from the TA sensor (sn L1740420). This data was stored on the comparison datalogger instead of on the TA met CR1000 datalogger. The comparison was at 10-min interval, so I averaged the values to 30-minute intervals, pasted it into the .dat file, and uploaded it to the database. We'll now be able to fill Air T and RH gaps from other sites with the TA_met data.

Joe with 9 out of 12 AirT/RH sensors set up for testing. The last three sensor will go on the post supporting the flux sensors.
