NIM/MFRSR/M1 - Instrument not shading properly

Shadowband not shading properly between 0830 and 1500.  Do not use diffuse or direct data 
in this range.  Maintenance on 2/1/2006 resolved the problem.

NIM/SKYRAD/M1 - IRTs do not agree with AERI

Since deployment at PYE, and then at NIM, the AMF SKYRAD IRT measured about 10K higher sky 
temperatures than the AERI and the MWRP IRT measureed about 20K higher than the AERI.  
Several actions were taken to diagnose the problem including confirming the correct 
configuration of the IRTs and data logger, cleaning the mirror and lens, and replacing the mirror.

After several days of rain beginning 6/2/2006, the three instruments came into agreement. 
It is unknown whether this was a problem with the AERI, MWRP-IRT or SKYRAD-IRT.

NIM/MPL/M1 - False Positive Cloud Base Height Values During Solar Noon

As the laser ages, the output reduces.  This lowers the signal to noise ratio. The lower 
signal to noise ratio interferes with the cloud base height algorithm to correctly 
determine if a cloud is actually present. During solar noon the signal to noise ratio is the 
lowest. This condition results in many false positive values. The values start at a high 
altitude and progressively get lower as the sun gets to zenith. The trend reverses as the 
sun passes. The pattern in the data resembles a ?V? shape starting 2 hours before solar 
noon to 2 hour past. A low incident of false positive values exists from 20051227. However, 
the condition becomes prominent on 20060303 - 20060420. The cloud base calibration table 
was modified to compensate for the lower signal to noise levels. 

Note: If a cloud is actually present, the cloud base algorithm will determine the height 
and report correctly. The false positive values are only a concern during cloud free 
conditions.

NIM/SKYRAD/M1 - Instrument ventilator problem

Data quality office first reported that PIR1 and PIR2 appear to be deviating more than 
typical during the daylight hours.  It was found that the Skyrad PIR ventilator fans were 
building up debris on the intake air filter.  Obstructed air flow results in solar heating 
of the PIR ventilator housing in the later part of the day and biasing the incomming IR 
irradiance values. The slow buildup was insidious and wasn't discovered and corrected 
(i.e. ventilator fans cleaned on a regular and frequent basis) until Feb 23rd. On or around 
December 23rd was when this problem may have first started.  We are unable to quantify the 
extent of the problem in W/m2.  Normal deviation between PIRs is typically 3-5 W/m2.

NIM/MWRP/M1 - Software problem

The MWRP computer failed and it was cloned with a new Gx620. Soon after, the MWRP program 
started to crash and was intermittent. Data were lost on March 3, 4, 5. 
On March 7 the program was forcefully ended and restarted. This appears to have cleared 
the problem. The instrument has been running since.

NIM/TSI/M1 - Reprocess: Data processing problem

Due to the high aerosol conditions at Niamey, the TSI appeared to be beyond the limits of 
processing the color JPEG image into cloud fraction values. Several attempts to adjust 
the sky filter values used to process the images did not yielded the desired results. The 
processed images indicate an opaque sky cover, even in the absence of clouds.

The problem was corrected by removing the neutral density filter from the lens and 
re-adjusting the sky filter values.

The data can be reprocessed.

NIM/MWRP/M1 - IRT Sensor Calibration

Discrepancies between the MWRP and Skyrad IRT were observed in January. The MWRP IRT 
readings were constantly higher than those of the skyrad IRT. Some changes were introduced to 
the MWRP IRT to address the problem (see DQR D060602.2). On May 3, the IRT mirror was 
replaced. After the change in the mirror, the MWRP IRT readings became about 5-8 C lower. On 
June 3 the agreement between MWRP and Skyrad IRT became satisfactory (2-5 degree C 
difference).

It is hard to numerically quantify the difference in the IRT readings caused by the change 
in the mirror. We can only warn the user that between January 1 and June 3 the MWRP 
readings are 8 to 15 degree higher than the skyrad IRT.

NIM/ECOR/M1 - CO2/H20 Fluxes Incorrect

The analog output of the CO2/H2O sensor was not being properly acquired by the sonic or 
the data acquisition system. 

CO2 and latent heat fluxes were therefore incorrect.  All other measurements
were correct.

• CO2 flux(fc)
• latent heat flux(lv_e)

NIM/MWRP/M1 - Reprocess: IRT configuration setting error

The infrared thermometer settings (IRT) were not configured as specified by the 
manufacturer. The analog output was set to a range of -60 to +50 C (0-10V) instead of -50 to +50 C 
(0-10V). The settings were changed on April 20. The IR temperatures should be slightly 
smaller than reported.

The following formula can be used to convert the wrong readings to the new:
    T_new = -60 + 1.1(T_old+50) 
where all temperatures are in degree C. For example, if T_old = 30 C, T_new = 28 C.

Spikes in Shaded 1 occur frequently during this time period, resulting in differences b/t 
shaded1 and shaded2 exceeding 20W/m2.  Instrument connections were checked and a spare 
PIR instrument was tried in the place of PIR1 (shaded1).  After returning the original PIR1 
to its original location data again looked good and very close to PIR2.  Problem appears 
resolved but exact cure is unknown.

NIM/TSI/M1 - Shadowband Misalignment

From installation, the shadowband was positioned south at solar noon until the vernal 
equinox when it began to migrate counter-clockwise until reaching east 37 days later on 4/26 
(about 9 days before mid-spring). The shadowband at solar noon continued to migrate until 
reaching its most northerly position (~15 deg) on the summer solstice (if everything was 
perfectly aligned, it probably would have been pointed north on this day). It then began 
to migrate clockwise and reached east again 56 days later on 8/16 (about 14 days after 
mid-summer). As expected, the shadowband reached its most southerly position on the 
autumnal equinox but was about 10 deg off of being due south. 

With the apparent alignment problem, I don't understand why the shadowband was mostly 
blocking the sun. When I started noticing this offset in May, I chose to leave it alone 
because I felt that adjusting the shadowband to where I thought it should be would cause it to 
not block the sun at either sunrise or sunset. 

The alignment was corrected on 9/29 (6 days after the day of the autumnal equinox).

NIM/MWRP/M1 - IRTs do not agree with AERI

Since deployment at PYE, and then at NIM, the AMF SKYRAD IRT measured about 10K higher sky 
temperatures than the AERI and the MWRP IRT measured about 20K higher than the AERI.  
Several actions were taken to diagnose the problem including confirming the correct 
configuration of the IRTs and data logger, cleaning the mirror and lens, and replacing the mirror.

After several days of rain beginning 6/2/2006, the three instruments came into agreement. 
It is unknown whether this was a problem with the AERI, MWRP-IRT or SKYRAD-IRT.

NIM/SKYRAD/M1 - Tracker inoperative

Starting on 9/12 the NIM radiometer tracker drifted enough due to sinking supports and a 
drifting clock that the direct normal measurments (NIP) and the downwelling hemispheric 
diffuse shortwave measurments (8-48) were adversely affected in the afternoon hours.  The 
shortwave hemispheric global instrument (PSP) and downelling hemispheric longwave shaded1 
and shaded2 (PIR) are unaffected by this problem. 

The tracker problem greatly affected direct measurements and affected the diffuse 
measurement to a lesser extent. There are no redundant measurements for these instruments.  
However, during this time range the data collected before local noon (aprox 1140GMT) for all 
shortwave Skyrad instruments appear to be good.

NIM/AOS/M1 - impactor switching in 10 micron mode

A wire came loose in the ball valve that switches between the two impactor size cuts. The 
impactor was stuck on the sub 10 micron size cut during this period of time. There was no 
data from the sub 1 micron size cut during this time. The flags in the edited data will 
be changed to reflect the correct aerosol size cut.
