Subject:	TWP/MWR/C1/C2 - Sun in the field of view
DataStreams:	twpmwrlosC1.b1, twpmwrlosC2.b1, twpmwrtipC1.a1, twpmwrtipC2.a1
Description:	Every day between around noon local time (usually between 1 and 2 AM UTC time) there is an increase in the brightness temperatures due to the sun in the field of view of the radiometer. The effect lasts less than an hour around local noon (usually between 1 and 2 AM UTC time). The effect appears as a smooth increase and decrease in brightness temperature.

Subject:	TWP/SMET/C1 - Reprocess: ORG Data has very small rainrate values
DataStreams:	twpsmet60sC1.b1
Description:	The ORG data is collected via analog signal and not digital. Therefore, we continuously collect data even when no rain is occurring. We also capture small events such as leaves, large bugs, dust, etc blowing through the measurement path. Because this discrete event occurs quickly the value is usually captured for 1 or 2 seconds. This value is then averaged to the minute producing rainrate on the order of .009 mm/hr or less. These values are not indicative of rain and should be removed from the record or summing over long periods can bias the climate record. We are reprocessing the data to remove these small values and are adjusting the collection program to remove them before ingest.

Subject:	TWP/SMET/C2 - Barometer failure
DataStreams:	twpsmet60sC2.b1
Description:	The atmos_pressure values were spiking high (up to 110 kPa) from 06:00 UTC on 02/04 until the data went missing at 10:44 UTC on 02/06 when the barometer failed completely. Barometer replaced 2/23.

Subject:	TWP/SMET/C1 - Missing RH, Barometer, and ORG data
DataStreams:	twpsmet60sC1.b1
Description:	Atmos_pressure data suddenly went missing on 03/02 at 07:34 UTC and consequently, the relative humidity data flatlined. Furthermore, after a sudden precipitation event when the max precip rate flag was tripped the TBRG total has not agreed with the comparison ORG or the precip rate plot. A loose wire connection was fixed 3/22 restoring RH and barometer data. A damaged cable was repaired 5/11 restoring ORG data.
