Description
The Campbell CR1000 logger program that controls the operation of the majority of ARM multifilter rotating shadowband radiometers (MFRSR) is being upgraded. Most significantly, the upgrade will add functionality for operation at locations greater than +/- 50 degrees latitude. This will allow us to complete the transition of the NSA MFRSR to the same state as the fully upgraded systems that are currently operating at the SGP sites. Other logger program updates include: adding code for seamless deployments in the Southern hemisphere, improved reading of the Dallas instrument identity chip, expanded internal documentation of the program, and an overall streamlining of the code. Once completed, the only required end user input is the station’s latitude and longitude; otherwise, system operation due to instrument location will be transparent to the end user. In addition to the above updates, we are also proposing additional changes that we believe will improve the primary measurements, as well as including unique QC parameters to better assess the stability of a given measurement set.
By the time of the 2012 ASR Science Team Meeting, we will also have completed an upgrade of the SGP Central Facility (CF) multifilter radiometers (MFR). Those instruments are known as MFR10m and MFR25m. This will be a complete update of those systems, i.e, both will have fully refurbished sensors, and data will be collected with Campbell CR1000 data loggers. Where applicable, software updates to the MFRSR code will also be incorporated into the MFR logger program.
In addition to the Central Facility MFR upgrades, we are also resurrecting the MFR that flies on the Cessna out of the Ponca City airport. This instrument will use the same code as the CF MFRs, and the instrument system will also include a GPS for time and location (lattitude/longitude/altitude) information. The Cessna MFR should be functional no later than the Science Team Meeting.
All of the above changes (planned and proposed) will be completely described in our poster.
