“…In the study areas average annual temperatures are recorded between 22 and 26°C, with an average annual rainfall of 700mm, rainy season from April to September, relative air humidity between 60 and 80% and average atmospheric pressure around 950hPa, with small annual amplitude due to small temperature variations (AZEVEDO et al, 2015;BRASIL, 2010;MACEDO et al, 2011;SOUZA et al, 2006). Identification and evaluation of flora gas exchange For the delimitation of the sample area we used GPS Garmin Gpsmap 62sc 5mp camera, satellite images, trenas, stakes and zebra tape, besides other materials needed for the study, such as: annotation block, Canon powershot SX60HS 16.1MP digital camera LCD 3.0, 65x optical zoom, digital geoprocessing software (ArcMap, 2011, licensed the Laboratory of Digital Cartography, Geoprocessing and Remote Sensing -CADIGEOS, of the Postgraduate Courses of the Humanities Center of the Federal University of Campina Grande -UFCG).…”
