Results of the study of the urban heat island over Nizhni Novgorod on the basis of data from mobile and stationary microwave temperature profilers are presented. The stationary temperature profiler MTP-5 was installed in the city center. The profiler provides continuous temperature measurements in the altitude range from 0 to 600 m with accuracy 0.5°C and with the cycle of measurement 5 min. The mobile version of the MTP-5 instrument (MMTP-5) provides measurements at 17 points including 11 inside the city and 6 in the suburb. Measurements were taken under anticyclone conditions mostly at night and in the morning on August 6 and 7, September 1, and October 16–18, 2004.
