NWSChat – NOAA’s National Weather Service
THE NATIONAL WEATHER SERVICE RECONDITIONING CENTER (NWSRC) REPLACED THE AUTOMATED SURFACE OBSERVING SYSTEM THERMOMETER AND ASSOCIATED ELECTRONICS AT THE ALBANY INTERNATIONAL AIRPORT YESTERDAY, SEPTEMBER 29, 2021 AT 9:30 AM. THE THERMOMETER WAS REPLACED WITH A MODIFIED SENSOR AND CALIBRATED WITH A MODIFIED ALIGNMENT PROCEDURE.
A REFERENCE THERMOMETER, RUNNING SIDE BY SIDE WITH THE ASOS THERMOMETER, HAS COLLECTED DATA FOR COMPARISON SINCE JUNE. THE PREVIOUS THERMOMETERS INSTALLED SINCE JULY 17, 2020 LIKELY HAD A COLD BIAS (THERMOMETER RECORDS A COLDER TEMPERATURE THAN THE ACTUAL TEMPERATURE).
THE NATIONAL WEATHER SERVICE WILL CONTINUE THE INVESTIGATION ON THE COLD BIAS IN THE ALBANY TEMPERATURE RECORD FOR THE PERIOD JULY 17, 2020 THROUGH SEPTEMBER 29, 2021.
