Subject:	SGP/MFRSR/C1 - Out-of-band filter leakage
DataStreams:	sgpmfrsrC1.a0, 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.

Subject:	SGP/MFRSR/E13 - Shadowband misalignment
DataStreams:	sgpmfrsrE13.b1, sgpmfrsrE13.a0
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 Site Power Outage Due to Winter Storm
DataStreams:	sgpmfrsrE13.a0, sgpmfrsrE13.b1, sgpmfrsrC1.b1, sgpmfrsrC1.a0
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, sgpmfrsrE13.a0
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.a0, 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.

Description:	On 5/12 and 5/13 the MFRSR (E13) had shading problems. These problems only affect the direct beam and diffuse radiation fields. 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.
