14 March 1996:
Presently, actions are proceeding along three fronts in the establishment of the ABLE:
Following approvals and contract negotiations, installation of small (6' X 8') trailers for radar and sodar equipment and pads for instrument location, etc. will begin. At present, the target date for instrument input is end of May, 1996. The ARM profiler is not expected to appear until mid-July at the earliest.
Minisodars are to be colocated with the wind profilers. The enclosures have already been constructed; they await the installation of phased array antennae and integration with computers, etc. They are expected to be ready by the May time frame.
One eddy flux station is expected to be purchased this fiscal year to be installed at the central site.
Future instrumentation includes surface meteorological and soil moisture stations, additional eddy flux stations, and a radiosonde system.
25 October 1996:
Starting September 16, 1996, the ANL 915 MHz radar was taken down and the ARM 915 MHz radar was installed in it's place. The radar and sodar at Beaumont are now both installed more permanently. For the time being, radar and sodar data are retrieved via modem under ANL control.
3 December 1996:
On November 20, 1996, the Sun Sparc was installed at Beaumont for collecting radar data. Consensus data products were not flowing until November 27th. Moments data products are yet to be available. Sodar data products continue unaffected.
16 December 1996:
On December 5, 1996, Beaumont radar moments data begins to become available.
17 March 1997:
On February 21, 1997, BLRS 915 MHz RADAR/RASS system and mini-SODAR were installed at Oxford site. Data links are not installed yet. (Oxford sodar was not operational until April 16, 1997).
23 May 1997:
Whitewater, Beaumont, and Oxford are all operating as remote sensing sites. Each has 915 Mhz radar with RASS and miniSodar. AWS (surface met stations) are operational at Beaumont, Oxford, and Smileyberg. Eddy correlation station with momentum and heat flux also operating at Smileyberg. Data transfers are hourly to Augusta and ANL. Primary web server for data display is http://www.atmos.anl.gov/ABLE/
30 January 1998:
As of September 26, 1997, all data hub and office functions were moved to the Central Site on Haverhill Road. We seem to finally be on track to start development of the Whitewater "permanent" site. Instruments at Whitewater have been at a temporary site since first installed during April 1997. Since about November 11, 1997 we have had a period of usable CO2 and moisture fluxes at Smileyberg.
29 April 1998:
Instrumentation has been dismantled at the Whitewater site to begin construction of the new "permanent" site. Data should be available as of June 22, 1998.
15 July 1998:
The 915 MHz radar with RASS and miniSODAR were re-deployed at the new Whitewater "permanent" site. Data flow started again on June 25, 1998. AWS and TDR systems should follow before the snow flies. Whitewater has been converted over to an ISDN data link. Only Beaumont remains as POTS (plain old telephone system).
2 September 1998:
The Oxford BLRS radar system is down for repair. The final 915 MHz amp is being evaluated. Some of the current activities: Augusta Central Site is being further developed with a trailer move and AWS pad installation. The Whitewater site is being further developed by adding an AWS pad and a TDR soil moisture array. A second ECOR system is in the procurement phase.
30 October 1998:
On October 27, 1998 the Augusta APO AWS started to collect data. On October 29, 1998 the Whitewater AWS started to collect data. Negotiations are underway to secure use of a site two miles south-east of Rose Hill as a second eddy correllation site.
26 April 1999:
On December 16, 1998 a new LAP-3000 four panel, five beam radar system was installed at Oxford. The BLRS system, which had been running at Oxford, was moved to the Central Site and run for a one month trial starting on March 19. On April 23, 1999 the Beaumont site went to ISDN service. On April 26, 1999 the Whitewater radar was shut off for phase-shifter repair.
17 June 1999:
On May 19, 1999, the Whitewater radar was back online and collecting data. On May 19, 1999 several sensors were added to the Whitewater AWS data flow: IRsurface, Solar, Albedo, and Soil Moisture. On May 20, 1999 Whitewater EBBR data starts flowing. On May 25 several sensors were added to the Smileyberg AWS data flow: Soil Temperature, Soil Moisture, Soil Heat Flux, and PAR. On May 26, 1999 the Whitewater TDR data collection moved over to ABLE control. From June 14-17, 1999 the Whitewater radar was down for phase shifter repair.
