Atmospheric temperatures measurements for the height between 80 and 100 km from the ambipolar diffusion coefficient taken by meteor radar is a relatively new technique. However, due to lack of more accurate models of atmospheric pressure in the region, this technique has problems. Then it became necessary the development of a technique in which the temperature in the altitude where the highest count of meteors occurs is calculated from the temperature gradient. In this work the temperature was calculated for each day of observation between July 2004 and June 2009. The values were compared with temperature data from TIMED/SABER and OH (6,2) rotational temperature data obtained by multichannel photometer at the site of observation at São João do Cariri-PB (7,4°S; 36,5°W). The daily average annual temperature obtained by each equipment showed strong seasonal variation with maxima at the months near of the equinoxes, however, with averaged values very different. The average total obtained by the meteor radar SKiYMET was 226.2 K, higher than the average of other instruments. Mesospheric temperatures were subjected to spectral analysis and the results revealed the presence of oscillations of 80, 181.7, 274.5, 364 and 718 days in the meteor radar SKiYMET. For the rotational temperature, the observed oscillations were 183.1, 403.9 and 647 days. In the TIMED/SABER data, the oscillations detected in the three different analyzed altitudes were ~ 90, ~182.5 and ~ 365 days. These results were compared with those obtained elsewhere and reported in the literature.
