NSA/SKYRAD/C1 - IRT measurements during precipitation events
DataStreams:nsaskyrad60sC1.a1
Description:
The IRT measurement of sky/cloud temperature was in question during precipitation events 
because rain or snow could accumulate in the upward-pointed lens barrel. This was 
corrected by reorienting the IRT to measure the sky temperature as reflected by a gold mirror.
Measurements:nsaskyrad60sC1.a1:
  • Sky/Cloud Infra-Red Temperature(sky_ir_temp)
  • Sky/Cloud Infra-Red Temperature Standard Deviation(sky_ir_temp_std)
  • Sky/Cloud Infra-Red Temperature Maxima(sky_ir_temp_max)
  • Sky/Cloud Infra-Red Temperature Minima(sky_ir_temp_min)

NSA/SKYRAD/C1 - Noisy PIR data at Barrow
DataStreams:nsaskyrad60sC1.a1, nsaskyrad60sC1.b1
Description:
PIR1 data is noisy throughout the entire period, though there is still a definite signal 
through the noise.
Measurements:nsaskyrad60sC1.a1:
  • Downwelling Longwave Hemispheric Irradiance, Shaded Pyrgeometer1, Minima(down_long_hemisp_shaded1_min)
  • Downwelling Longwave Hemispheric Irradiance, Shaded Pyrgeometer1, Standard
    Deviation(down_long_hemisp_shaded1_std)
  • Downwelling Longwave Hemispheric Irradiance, Shaded Pyrgeometer1, Maxima(down_long_hemisp_shaded1_max)
  • Downwelling Longwave Hemispheric Irradiance, Shaded Pyrgeometer1(down_long_hemisp_shaded1)

NSA/SKYRAD/C1 - Tracker Inoperative
DataStreams:nsaskyrad60sC1.b1
Description:
A blown fuse resulted in the tracker not shading the PIR and B&W
and the NIP not following the sun.
Measurements:nsaskyrad60sC1.b1:
  • Downwelling Shortwave Diffuse Hemispheric Irradiance, Ventilated Pyranometer,
    Minima(down_short_diffuse_hemisp_min)
  • Downwelling Shortwave Diffuse Hemispheric Irradiance, Ventilated Pyranometer(down_short_diffuse_hemisp)
  • Shortwave Direct Normal Irradiance, Pyrheliometer, Minima(short_direct_normal_min)
  • Shortwave Direct Normal Irradiance, Pyrheliometer, Standard Deviation(short_direct_normal_std)
  • Shortwave Direct Normal Irradiance, Pyrheliometer, Maxima(short_direct_normal_max)
  • Downwelling Shortwave Diffuse Hemispheric Irradiance, Ventilated Pyranometer,
    Standard Deviation(down_short_diffuse_hemisp_std)
  • Downwelling Shortwave Diffuse Hemispheric Irradiance, Ventilated Pyranometer,
    Maxima(down_short_diffuse_hemisp_max)

NSA/SKYRAD/C1 - IRT insufficiently heated
DataStreams:nsaskyrad60sC1.a1
Description:
IRT had insufficient heating to maintain an internal reference temperature above 0 degrees 
C. Measurements of sky temperature were over-estimated when instrument was below 
freezing.
Measurements:nsaskyrad60sC1.a1:
  • IRT1 maximum(irt1_max)
  • IRT1 standard deviation(irt1_sd)
  • IRT1 minimum(irt1_min)
  • IRT1 mean(irt1_mean)
