Subject:	SGP/MFRSR/C1 - Out-of-band filter leakage
DataStreams:	sgpmfrsrC1.b1
Description:	Testing of the batch of centrovision filters being used in the MFRSR C1 instrument indicate that the first four filters leak 'out of band' light. The leakage for each filter is (1)415nm 3%, (2)500nm 1-2%, (3)615nm 1-2%, (4)673nm 3%. Acceptable leakage is less than 0.5%. This leakage causes an error in the irradiance values (too high) at these four wavelengths and the optical depths calculated using this data will be too high.

Description:	Massive shading issue on 12/16 through 12/18. It was obviously found and resolved on 12/18. On 12/22 it looks like the shadowband stops functioning altogether. (It is likely it slipped on the motor shaft.) It continues like this until 12/28 @ 1630 when an attempt was made fix the problem. This was somewhat successful, but there is still a shading problem in the afternoon between 1730 and 2300 until 01/09/2008. Some data from 12/28/2007 - 01/09/2008 will be OK. Don't use data between the hours 1730 and 2300. Avoid data from other dates described in this DQR.

Subject:	SGP/MFRSR/E13 - Shadowband misalignment
DataStreams:	sgpmfrsrE13.b1
Description:	Between 20071216 and 20080225 there are four stretches where the instrument is not shading properly. Those periods have been accurately designated in this DQR. Data outside these ranges are OK. Avoid using this instrument during times covered by this DQR. The hemispheric data may be OK, but with other good choices (C1 MFRSR and NIMFR), it is suggested to just avoid E13.

Subject:	SGP/AOD/ALL - Reprocessing Notice (RID 1212)
DataStreams:	sgpmfrsraod1michC1.c1, sgpmfrsraod1michE13.c1
Description:	See below for details of reprocessing that was completed on 20160127. Original DQR category: 4 (Red, Incorrect). ----------------------------------------------------------- For reasons not entirely understood, on or about Oct 28, 2012 the MFRSR AOD Value Added Product began to experience infrequent but serious data corruption issues. This is evident in the data files from SGP as irradiance fields, calibrations, and AODs taking nonsense values sometimes NaN, Inf, or other values orders of magnitude out of bounds with normal behavior. The behavior is sometimes abrupt with drastic changes observed from one day to the next, but not within a given day. This behavior was not reproducible when reprocessing on the development system. We have developed a new version of the MFRSR AOD Value Added Product using a different library suite and have confirmed successful reproduction of the existing product when the existing product was not corrupt, and consistent replacement of the corrupt periods with reliable results.

In reality, the values are set to -1 and will not be filtered out by programs that automatically remove missing values. This will be fixed in a future reprocessing task.

Subject:	SGP Site Power Outage Due to Winter Storm
DataStreams:	sgpmfrsrE13.b1, sgpmfrsrC1.b1
Description:	On Saturday and Sunday, December 26 and 27th a powerful winter storm (Goliath) brought sleet and freezing rain to much of Oklahoma with wind gusts of 45 MPH at times. The result was very very slick roads and mass power outages. The SGP central facility lost power at 8:55 PM CDT on Sunday, December 27th. The power was restored on 7:56 PM CDT on Wednesday, December 30th Site Emergency procedures were activated and Technicians drained water out of instrument reservoirs and other measures as needed, early Monday morning. On Wednesdays as roads and power started was restored to much of the areas east of I-35 , Site Technicians performed maintenance on several Extended Facilities. During this period, data are potentially missing, incorrect, or suspect. Carefully inspect the data before use.

Subject:	SGP/MFRSR/E13 - Shadowband misalignment
DataStreams:	sgpmfrsrE13.b1
Description:	The E13 MFRSR developed a shading problem on or about 05/04. (The exact date when this problem started is difficult to pin down exactly.) The shading problem is easy to identify on a clear day because plots of direct beam and diffuse irradiance versus time become "fuzzy". The total irradiance is not affected. In response to the shading problem, a whole sequence of events then ensued: these actions were designed to solve the shading problem but did not succeed until the very end. Here's a rundown of what took place: 98/05/11 - shadowband adjustment was made at 1544 GMT - this adjustment corrected the shading problem that occurred in the morning, but inadvertently caused a PM shading problem 98/05/20 - shadowband adjustment at 1804 GMT 98/05/21 - shadowband adjustment at 1630 GMT 98/06/01 - shadowband adjustment at 1910 GMT 98/06/02 - shadowband adjustmnet at 1550 GMT Alas, these adjustments did not solve the shading problem and it seemed to get worse (for example, on 06/11 the shading is VERY BAD from sunup until about 1500 LST). 98/06/16 - shadowband adjustment at 1715 GMT This final adjustment seems to a solved the problem!

Subject:	SGP/MFRSR/C1 - Irradiances too high
DataStreams:	sgpmfrsrC1.b1
Description:	After the A/D convertor lock-up was corrected on 981014, the irradiances as measured by the MFRSR were about 20% too high. 981018 is a particular egregious example of measured irradiances that are too large. Cause of the problem is not known, though suspect some moisture got into the instrument (this was a period of much precipitation). After 981024, the MFRSR settled down and the irradiances returned to a normal range.

You can see the problem vividly by looking at the direct beam (and diffuse radiation) for 5/12 -- you'll see a fuzziness in these fields centered about local noon. The shading problem was solved on about 05/13 at 2000 GMT.
