Subject: | PYE/ECOR/M1 - Reprocessed: Wind direction offset corrected |
DataStreams: | pye30ecorM1.b1 |
Description: | The SMET wind direction was consistently 15 to 20 degrees larger than the wind direction determined by the ECOR. The ECOR was mistakenly aligned to magnetic north during this period. The magnetic declination is 14 deg. 58 min., which explains most of the difference. The ECOR data for this period were reprocessed in November 2006 to add 15 degrees to the wind direction. No other changes were made to the data. The reprocessed data were archived in January 2007. |

Subject: | NIM/TSI/M1 - Reprocess: Data processing problem |
DataStreams: | nimtsicldmaskM1.a1, nimtsiskycoverM1.b1 |
Description: | 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. |

Subject: | NIM/TSI/M1 - Shadowband glare |
DataStreams: | nimtsiskycoverM1.b1 |
Description: | When the neutral density filter was removed from the lens, the reflection of the sun from the smooth shadowband strip became much brighter causing a glare in the image on clear days. To minimize this reflection, a rough surface (the "fuzzy" side of an adhesive velco strip) was placed along the length of the shadowband. |

Subject: | PYE/ECOR/M1 - Flux Data Suspect For Some Wind Directions |
DataStreams: | pye30ecorM1.b1 |
Description: | For some wind directions the horizontal fetch was not representative of the field in which the AMF was located. Therefore, for the wind direction ranges 66-92 (buildings and trees) degrees, the fluxes are affected by insufficient fetch and surfaces, buildings, or vegetation that are not similar to the local field conditions. |
