Affected Datastreams: | sgppgsC1.b1 |
Description | Precise Gas system (PGS) data at 60m (channel 4) are incorrect. This problem is due to a freezing rain and ice storm that hit SGP Central facility on January 5, 2005. The 60m tower inlet was clogged with ice and consequently, no air was supplied to the PGS instrument. |

Affected Datastreams: | sgppgsC1.b1 |
Description | Time Variables - to make the PGS system more consistent with LBNL's other data streams, the variable 'yyyymmddhhmmss' was renamed 'yyyydddhhmmss'. Also, at the bottom of each file, variables 'yyyy','mon','hour','min' were added for those users who prefer to use these variables instead. The new 'time' variable (seconds since midnight of the start of file) was added to make files compatible with the new recommendations. Quality Control Flags - to prevent confusion, the quality control flags 'qc_co2ppm' and 'qc_sum_co2' were combined. The flag 'qc_sum_co2' was elliminated and 'qc_co2ppm' now performs range checking on 'co2ppm' variable as well as checking values of all dependencies' qc flags. |

Affected Datastreams: | enaaosghgC1.a1 |
Description | The mentor has requested the addition of a 'height' global attribute to record the inlet height. The inlet for the ENA AOSGHG has always been at a height of 10 meters, but the datastreams did not have this new global attribute. Both the aosghg.a1 and aosghgaux.a1 datastreams will be updated to add this new global attribute. The mentor has requested that the entire dataset be reprocessed to make this addition to the global attributes. We will be releasing dowstream aosghg.b0 and aosghg.b1 processing that will incorporate this new global attribute from the a1 input datastreams. |
