It is known that different types of land use and occupation (urban, industrial, rural, forest) alter the balance of energy between the surface and the atmosphere. The comparison between surface and sub-altitude climatology data in urban and rural areas has still been few studied. In this way, the proposed study aims to analyze and compare the values of temperature and relative humidity of the air near the surface (1.5m high) and at different heights (50m and 190m of the surface) in urban and rural areas in Sao Carlos (SP), during nighttime in winter episodes, by means of  termo-hygrometer coupled in a quadricopter (four propellers) Remotely-Piloted Aircraft (RPA/Drone). The flight in the urban area was carried out on 07/13/2018 and in the rural area on 07/26/2018 between 19:30 and 20:30. The results showed that in the urban area at night time the temperature and relative humidity of the air are higher near the surface in relation to the sub-altitude data. In the rural area at night time the air temperature is lower and the relative air humidity is higher to the surface compared to the sub-altitude data.
