Este trabalho buscou realizar um estudo de caso da variação da temperatura do solo (TS) em dois biomas florestais, floresta amazônica e mata atlântica, para um mês considerado chuvoso e outro seco. Para a área da floresta amazônica, foram utilizados dados da torre K34 do grupo de micrometeorológica do LBA-INPA, localizada na Reserva Biológica do Cuieiras, e analisando os perfis de temperatura do solo através de sensores MCM 101 (IMAG-DLO, Wageningen The Netherlands) nas profundidades 2, 5, 10, 20 e 50 cm, para o mês de abril (chuvoso) e setembro (seco) de 2009. Na área de mata atlântica os dados foram obtidos através de uma torre micrometeorológica de 26 m de altura localizada na cidade de Coruripe-AL, e analisando os perfis de temperatura do solo através de termopares tipo cobre/constantan nas profundidades 1, 5, 10, 20, e 50 cm, para o mês de junho (chuvoso) e novembro (seco) de 2009. Observou-se que a variabilidade TS dentro da floresta amazônica apresenta pouca oscilações diária, tanto para o período seco (4 ºC), quanto para o chuvoso (1,2 ºC). Enquanto que a mata atlântica mostrou variabilidade distinta entre os períodos, o período seco obteve máxima amplitude (18 °C) e o período chuvoso teve pouca variação (1 °C). A B S T R A C T This work sought to accomplish case study of the variation of soil temperature (TS) in two forest biomes, Amazon rainforest and Atlantic forest for a month under consideration rainy and a dry. For the area of the Amazon rainforest, we used data from the K34 tower of the group of micrometeorological LBA-INPA, located in the Biological Reserve Cuieiras and analyzing the profiles of soil temperature sensors through 101 MCM (IMAG-DLO, Wageningen The Netherlands ) in the depths of 2, 5, 10, 20 and 50 cm, for the month of April (rainy) and September (dry) 2009. In the area of Atlantic forest the data were obtained through a micrometeorological tower 26 m high located in the city of Coruripe-AL, and analyzing the profiles of soil temperature using thermocouples type copper / constantan in the depths of 1, 5, 10, 20, and 50 cm for the month of June (rainy) and November (dry) 2009. It was observed that TS variability within the Amazon rainforest has little daily oscillations for both the dry period (4 °C), and for the rainy period (1,2 °C). While the Atlantic forest showed distinct variability between periods, the dry obtained maximum amplitude (18 °C) and rainy had little variation (1 °C).
