The Operational test and Evaluation for the ASOS software upgrade 2.6 has been completed. The installation of version 2.6 will begin in mid August for non-towered ASOS sites and will begin in mid-October at towered sites. Installations will continue at the rate of one one to two sites per WFO per week, depending on the weather, through next spring.
The FAA expects to make ALDARS (lightning data) available in all FAA ASOS's in October 1999. The version 2.6 software allows ALDARS information to be displayed in the body and remarks sections of the ASOS observation.
The Western Region Climate Center (WRCC) has moved to a new location. Note the new address:
WRCC-Desert Research Institute
2215 Raggio Parkway
Reno, Nevada 89512-1095
Phone: 775-674-7010
Facsimile: 775-674-7016
The NWS Office of Meteorology has issued an updated action item report from the April 1999 workshop at NWS headquarters. Click here for the document.
The non-commissioned ASOS that had been on the roof of the Los Angeles Civic Center has been moved to the ground level of the USC Campus and was commissioned on June 24th, 1999. The new site is within 5 miles of the Los Angeles Civic Center and is climatologically compatible. The identifier remains the same- CQT.
July ASOS commissionings include:
| 7R1 | Venice, LA |
| AEX | Alexandria, LA |
| AOO | Altoona, PA |
| BBW | Boken Bow, NE |
| DYL | Doylestown, PA |
| EVW | Evanston, WY |
| FPR | Fort Pierce, FL |
| IGX | Chapel Hill, NC |
| OLS | Nogales, AZ |
| WST | Westerly, RI |
New AWOS Sites on FOS include SVC-Silver City, NM and UKF-North Wilksboro, NC.
Here are some latitudes/longitudes and identifier changes for new AWOS stations:

Bill Conway of the National Severe Storms Laboratory (NSSL) is looking for feedback from the WSR 88D operational user community. NSSL has developed a new technique to mitigate the the problems of velocity range folding and velocity dealiasing errors in WSR 88D data. The technique is known as the multi-pulse repetition frequency dealiasing algorithm (MPDA). Multiple scans of data are collected at a constant elevation angle using different Nyquist velocities. The scans are merged and dealiased. The technique is mature enough to ask for user feedback and a home page has been developed for the operational meteorological community to do just that. The purpose of the algorithm is to provide as immediate solution to the problems of range folding. And velocity aliasing using the open radar products generator (RPG). Please feel free to review the web page and provide comments at http://www.nssl.noaa.gov/~conway/mpda_webpage/index.html.
