Subject:	SGP/SONDE/C1 - Increased precision for alt, dp, pres, rh, tdry
DataStreams:	sgpsondewnpnC1.b1
Description:	The output precision of the following variables was increased 20060928 alt changed from 1m to 0.1m dp changed from 0.1degC to 0.01degC pres changed from 0.1 hPa to 0.01 hPa RH changed from 1%RH to 0.01%RH tdry changed from .1degC to 0.01degC Note that the increase in precision does not necessarily imply an increase in accuracy. Users are cautioned to continue to use their best scientific judgement when using these or any other data.

Subject:	SGP/MERGESONDE/C1 - Reprocess: Precip data incorrect
DataStreams:	sgpmergesonde1maceC1.c1
Description:	All precip values are incorrectly reported during the period: From 20060101-20101231 all precip values are incorrectly reported as missing, or -9999. From 20110101-present all precip values are reported as 0 even though the qc_precip variable flags the data as missing, or -9999. The precipitation data from the co-located surface met station were not actually missing, but the MERGESONDE VAP did not properly ingest these data. While the 0 precip values reported after 20110101 in MERGESONDE may be correct on days with no precip, they are not actually tied to the measurements from the co-located rain gauge and are due to a VAP software error. To correct this issue, the MERGESONDE software will need to be corrected so the data can be reprocessed. Because precip is a secondary variable in MERGESONDE, this issue is considered low priority and the VAP will not be reprocessed until a sufficient number of issues in the VAP have been identified.
Measurements:	sgpmergesonde1maceC1.c1: Precipitation, total(precip)

Subject:	SGP/RLPROF/C1 - Reprocess: VAP error
DataStreams:	sgp10rlprofbe1newsC1.c1, sgp10rlprofbe1newsC1.s1, sgp10rlprofmr1turnC1.c1
Description:	Outdated and/or incorrect overlap correction files were used in original processing of the water vapor mixing ratio data (rlprofmr1turn). The overlap files have recently been updated. The VAP will be reprocessed with the updated overlap files.

DataStreams:	sgpsashenirhisunC1.a0, sgpsashenirlowsunC1.a0, sgpsashevishisunC1.a0, sgpsashevislowsunC1.a0
Description:	Occasional banding issues affect the SASHe data during this time period. At this time we have no automated means of identifying these periods but visual comparison with the collocated MFRSR is often definitive.
