Subject: | GRW/SKYRAD/M1 - Reprocessed: IRT configuration |
DataStreams: | grwskyrad60sM1.b1 |
Description: | The SKYRAD IRT was used in testing a revised serial communication program. During the testing, the analog output configuration was to changed to default values (used at TWP and NSA sites) that are different than those used at AMF. So, the IRT's analog output was set to a scale of 25K/V and an offset of 213.2K but the logger converted the signal using a scale of 26K/V and an offset of 173.2K. The sky temperature measurements were corrected using the following equation Tnew = (25/26)(Told-173.2K)+213.2K and the data were reprocessed. The reprocessed data were archived in April 2011. |

Subject: | GRW/SKYRAD/M1 - Possible dirty dome |
DataStreams: | grwskyrad60sM1.b1 |
Description: | The difference between downwelling shortwave hemispheric irradiance and derived downwelling shortwave hemispheric irradiance was larger than normal (>50W/m2) and was most noticeable at lower zenith angles. The problem spontaneously resolved itself on 7/16 without any specific callouts by the GRW cleaning personnel on their reports. Short_direct_normal datastream is suspected to be low due to potentially dirty NIP instrument window during this time period. The commencement of this problem corresponds with a rain event early 7/12. The possibility of other radiometers affected by dirty domes is also possible. Longwave instruments are typically immune to this level of contamination. |

Subject: | GRW/SKYRAD/M1 - Daily brief instrument shading |
DataStreams: | grwskyrad60sM1.b1 |
Description: | Due to the persistent cloudy conditions at this site this shading of the NIP and PSP is rarely evident in the data. But from approximately 1745 to 1810 GMT from 8/26 to 10/23 and from 3/01 to 4/18 during the AMF deployment years 2009 and 2010, the NIP and PSP are shaded by the 10m met tower to the SE of the Skystand. Data review indicates that the NIP (short_direct_normal) and PSP (down_short_hemisp) are shaded by a single tower pole and possibly other tower mounted objects. The data are not correctable but the azimuth and zenith windows to avoid are: short_direct_normal (NIP instrument) Zenith angle > 62 deg 254 deg < Azimuth angle < 262 deg primary obstruction at 255 deg Az down_short_diffuse(PSP instrument) Zenith angle > 59 deg 246 deg < Azimuth angle < 257 deg primary obstruction at 251.5 deg Az Date ranges this problem will exist for are: 20090301-20090418 (pre-official deployment, data exist) 20090826-20091023 20100301-20100418 20100826-20101023 The QCrad VAP should flag bad data points via its QC logic. Users should either exclude the data within the windows above or review data for outliers in these zenith, azimuth angles. |

DataStreams: | grwskyrad60sM1.b1 |
Description: | Due to the persistent cloudy conditions at this site the shading is rarely evident in the data. But at approximately 1010GMT everyday during from approximately 12/2/2009 to 1/11/2010 the NIP is shaded by the AOS tower. Data review indicates that only the NIP (short_direct_normal) is obstructed when the sun is at 130 to 132 deg azimuth during the time period specified. NIP data are not recoverable. However, short_direct_normal can be reconstructed by applying the following formula: Short_direct_normal = (down_short_hemisp-down_short_diffuse_hemisp)/cos(Zenith angle) |

Subject: | GRW/SKYRAD/M1 - Short direct normal questionable |
DataStreams: | grwskyrad60sM1.b1 |
Description: | Starting on 05/08/2010 values of short_direct_normal from the NIP instrument were reading low (up to 50W/m2). This was most apparent during sunny/partly sunny periods. The values spontaneously returned to normal on 5/14 with no Ops intervention. Data system checks after that date revealed no apparent problems with instruments or datalogger. The problem has not recurred. Only the short_direct_normal values during this time period are suspect. If direct normal values are needed they can be re-constructed using the following relationship for each minute of data: down_short_hemisp = short_direct_normal * cos(zenith angle) + down_short_diffuse_hemisp |

Description: | The current dlprofwind4news VAP generates time- and height-resolved estimates of wind speed, wind direction, and corresponding uncertainties from Doppler lidar PPI scans. A recent comparison with a heavily instrumented tall tower (BAO) has shown that the error estimates are biased low and exhibit poor correlation with the observed lidar-tower differences. We note that the measurements themselves (i.e. wind speed and direction) are minimally affected by this issue. |
