08/23/2009	1200	10/31/2009	2000	Incorrect

Subject:	SGP/NIMFR/C1 - Noise in 500nm channel
DataStreams:	sgpnimfrC1.b1
Description:	The 500nm channel data were noisy at times, and at other times output "steps down" a notch. On 10/14, maintenance was performed to re-seat connection. On 10/31, the noise returned briefly, so the end-date has been extended through that date.
Measurements:	sgpnimfrC1.b1: Altitude above mean sea level(alt) direct_horizontal_narrowband_filter2 Direct normal narrowband irradiance, filter 2(direct_normal_narrowband_filter2)

Subject:	SGP/NIMFR/C1 - Tube heater
DataStreams:	sgpnimfrC1.b1
Description:	The function of the tube heater is to prevent dew from forming on the front window. During this period the tube heater was not functioning, there were no reports of dew, and there were no indications in the data that dew on the window was affecting data.
Measurements:	sgpnimfrC1.b1: cosine_solar_zenith_angle Altitude above mean sea level(alt) direct_horizontal_broadband offset_filter6 offset_filter5 head_temp wavelength_filter6 wavelength_filter5 wavelength_filter4 wavelength_filter3 wavelength_filter2 wavelength_filter1 Radiation, shortwave, direct normal irradiance, 415 nm wavelength(direct_normal_narrowband_filter1) Direct normal narrowband irradiance, filter 3(direct_normal_narrowband_filter3) Direct normal narrowband irradiance, filter 2(direct_normal_narrowband_filter2) Direct normal narrowband irradiance, filter 5(direct_normal_narrowband_filter5) solar_zenith_angle Radiation, shortwave, direct normal irradiance, 673 nm wavelength(direct_normal_narrowband_filter4) East longitude(lon) head_temp2 North latitude(lat) nominal_calibration_factor_filter2 nominal_calibration_factor_filter1 nominal_calibration_factor_filter4 nominal_calibration_factor_filter3 nominal_calibration_factor_filter6 nominal_calibration_factor_filter5 nominal_calibration_factor_broadband normalized_transmittance_filter6 normalized_transmittance_filter5 direct_horizontal_narrowband_filter1 direct_horizontal_narrowband_filter2 normalized_transmittance_filter2 normalized_transmittance_filter1 time_offset normalized_transmittance_filter4 time Direct Normal Broadband Irradiance, broadband scale applied(direct_normal_broadband) normalized_transmittance_filter3 Direct normal narrowband irradiance, filter 6(direct_normal_narrowband_filter6) base_time tube_temp logger_volt offset_broadband azimuth_angle airmass elevation_angle offset_filter1 offset_filter2 offset_filter3 offset_filter4 direct_horizontal_narrowband_filter6 direct_horizontal_narrowband_filter5 direct_horizontal_narrowband_filter4 direct_horizontal_narrowband_filter3

Subject:	SGP/NIMFR/C1 - General instrument problem(s)
DataStreams:	sgpnimfrC1.b1
Description:	The instrument started showing signs of degradation, particularly in channels 5 and 6. There were also other issues noted such as connectors in poor condition. Taken together, it was decided to build a new instrument. The new instrument was installed on 20130819.
Measurements:	sgpnimfrC1.b1: direct_horizontal_narrowband_filter1 direct_horizontal_narrowband_filter2 Radiation, shortwave, direct normal irradiance, 415 nm wavelength(direct_normal_narrowband_filter1) direct_horizontal_broadband Direct Normal Broadband Irradiance, broadband scale applied(direct_normal_broadband) Direct normal narrowband irradiance, filter 3(direct_normal_narrowband_filter3) Direct normal narrowband irradiance, filter 2(direct_normal_narrowband_filter2) Direct normal narrowband irradiance, filter 5(direct_normal_narrowband_filter5) Radiation, shortwave, direct normal irradiance, 673 nm wavelength(direct_normal_narrowband_filter4) direct_horizontal_narrowband_filter6 direct_horizontal_narrowband_filter5 direct_horizontal_narrowband_filter4 direct_horizontal_narrowband_filter3 Direct normal narrowband irradiance, filter 6(direct_normal_narrowband_filter6)

08/19/2013	2051	08/26/2013	1825	Suspect

Subject:	SGP/NIMFR/C1 - Heater problem
DataStreams:	sgpnimfrC1.b1
Description:	The head heater is not working. After the new NIMFR was installed it was discovered the head temperature was not functioning. Heater was fixed and the instrument returned to service on 20130826. The irradiance data may be usable as the ambient temps are rather high this time of year. Coloring this DQR yellow with that in mind.
Measurements:	sgpnimfrC1.b1: direct_horizontal_narrowband_filter1 direct_horizontal_narrowband_filter2 Radiation, shortwave, direct normal irradiance, 415 nm wavelength(direct_normal_narrowband_filter1) direct_horizontal_broadband Direct Normal Broadband Irradiance, broadband scale applied(direct_normal_broadband) Direct normal narrowband irradiance, filter 3(direct_normal_narrowband_filter3) Direct normal narrowband irradiance, filter 2(direct_normal_narrowband_filter2) Direct normal narrowband irradiance, filter 5(direct_normal_narrowband_filter5) Radiation, shortwave, direct normal irradiance, 673 nm wavelength(direct_normal_narrowband_filter4) direct_horizontal_narrowband_filter6 direct_horizontal_narrowband_filter5 direct_horizontal_narrowband_filter4 direct_horizontal_narrowband_filter3 Direct normal narrowband irradiance, filter 6(direct_normal_narrowband_filter6)
