Subject:
TWP/SMET/C2 - Negative rainfall rates
DataStreams:twpsmet60sC2.a1
Description:
Due to limitations of the Zeno dataloggers all voltage measurements
from the optical rain gauge (ORG) were converted to rainfall rates. 
This resulted in negative values for rain rates.  Any value below
0.10 mm/hr should be considered to be 0 mm/hr.  New dataloggers 
alleviated this problem.
Measurements:twpsmet60sC2.a1:
  • Precipitation standard deviation(precip_sd)
  • precipitation minimum(precip_min)
  • Precipitation mean(precip_mean)
  • Precipitation maximum(precip_max)

TWP/MPL/C2 - Reprocess: Incorrect longitude and altitude reported
DataStreams:twpmplC2.a1
Description:
The longitude of the MPL instrument is reported as -166.916.  The correct longitude is 
+166.916.

The altitude of the MPL instrument is reported as 7.2.  The correct altitude is 7.1 M.

These data will be reprocessed at a low priority.
