THE KLOT (CHICAGO IL)WSR-88D RADAR WAS RETURNED TO SERVICE
LATE MONDAY AFTERNOON.
HOWEVER, FURTHER CALIBRATION IS NEEDED. CURRENT DATA FROM
KLOT COMPARED TO WSR-88D DATA FROM NEIGHBORING NWS SITES
SHOWS THE KLOT WSR-88D TO NOW BE RUNNING APPROXIMATELY
5 TO 7 DBZ BELOW THAT MEASURED BY THESE OTHER RADARS. THIS
IS A CHANGE FROM PREVIOUSLY WHEN DATA WAS 10 TO 15 DBZ TOO
HIGH.
PLEASE REFER TO NEARBY WSR-88D RADARS KMKX (MILWAUKEE WI),
KGRR (GRAND RAPIDS MI), KIWX (NORTHERN IN), KDVN
(DAVENPORT IA), KILX (LINCOLN IL), KIND (INDIANAPOLIS IN)
AS WELL AS TERMINAL DOPPLER RADARS TORD (OHARE AIRPORT) AND
TMDW (MIDWAY AIRPORT) TO COMPARE REFLECTIVITY VALUES AND
REFLECTIVITY DERIVED PRODUCTS FROM THESE SITES TO THAT FROM
KLOT.
