Instrument Mentor Monthly Summary Report for MFRSR: 06/2009
1. Data Review:
M1 (Graciosa Island, GWR)
Data show a mild shading issue during the morning hours (sunrise - 0930).
***NSA***
C1 (Barrow)
Data collection began 20090504. Initial data show a possible shading problem at high zenith angles (0600 - 1500).
C2 (Atqasuk)
Data look fine the entire month.
***SGP***
C1
Data look fine the entire month.
E1
Data look fine the entire month.
E2
Data look fine the entire month.
E3
The month begins (continuing from prior months) looking terrible. An attempt was made to fix the instrument shading on 20090611. It helped some, but there is still a problem in the morning (sunrise - 1600 UTC). So, from the 11th forward, data AFTER 1600 UTC look OK.
E4
Data look fine the entire month.
E5
Data look fine the entire month.
E6
Data look fine the entire month.
E7
Data look fine the entire month.
E8
We see the very beginnings of a shading issue in June. Possibly the first day seen is 20090606 (1930 UTC - 2330 UTC), but the first we're sure is 20090616 (1930 - 2330). Cloudy conditions persist between the 6th and 16th, so we can't be positive of the first day. The situation continues through the end of the month.
E9
There was head temperature irregularity between 20090615 @ 0600 and 20090617 @ 0330. On the 16th, in particular, head temp gets pretty high. Irradiance data should not be used during this period. The rest of the month looks fine.
E10
Data look fine the entire month.
E11
Instrument began the month (continuing from the prior month) suffering from a shading issue in the afternoon hours (1900 UTC - sunset). Maintenance was performed on the 17th, and though improved, there is still a shading issue between 1830 and 2300 UTC. The drop outs seen in the open channel in prior months are not occurring in June.
E12
Data look fine the entire month.
E13
Data look fine the entire month.
E15
There is a feature to the data I've never seen before. Look at 20090616, 17-30. There is a distinct hump in the morning diffuse values. Maybe a positive reflection onto the instrument? We are investigating...
E16
Data look fine the entire month.
E18
The shading issue first reported in January continues into May until maintenance resolved the problem on 20090520. The affected hours are between 1800 and sunset. Data from the 20th forward look fine.
E19
Data look fine up until 20090618 @ 0630 UTC when the heater stops functioning. A non-functioning heater has a detrimental effect on the irradiance data. The mentor recommends not using data while the heater is not functional.
E20
Data look fine the entire month.
E22
Data look fine the entire month.
E24
The shading issue first reported in Feb continues into and through June. Another attempt was made to resolve the issue on 20090618, but there was minimal improvement, if any.
E27
We're seeing some sporadic drop outs in the temp data. Not sure if this in real, or a problem with a thermistor. The irradiance data does not appear to suffer, so possibly the issue is with the reading of the temperature.
***TWP***
C1 (Manus)
Data look fine the entire month.
C2 (Nauru)
The logger board failed on 20090606 @ 0300 UTC.
C3 (Darwin)
Data look fine the entire month.
2. Instrument Performance Issues and Trends:
3. Current Task Status:
ECR-00692 -- Purchase data loggers and heater controllers for MFRSRs. Essentially completed. The Campbell loggers and heater boards have been delivered. Tagging on to this ECR is a small order(s) that will be placed for miscellaneous small parts to shore up the MFRSR parts bins.
4. Near-Term Plans:
