Objective:-----The objective of this database is to measure and identify the seasonal variation of meteorological conditions at a site on the southern coastal line of Sonora, Mexico.This meteorological dataset is part of a larger project entitled "Seasonal variability of vertical exchange fluxes of CO2, water and energy in a semiarid mangrove site located in Northwestern Mexico".Both the project and the meteorological station are managed and operated by the Sonora Institute of Technology (ITSON) and funded by the National Laboratory of Coastal Resilience (LANRESC) with funding from the National Council of Science and Technology (CONACYT). ------------------Study site-----The meteorological tower is located at the coastal intertidal zone of the northern edge of Mazocarit Island, approximately 400 meters west of the Navopatia field station, both located in northwestern state of Sonora, México. The site is characterized by the presence of two dominant species of mangroves (Avicennia germinans and Rhizophora mangle) rooted on salt-silt-clayey sediments. The Mazocarit Island is found within the coastal lagoon system known as the Agiabampo-Bacorehuis-Rio Fuerte system encompassing an area of 90,804 ha in the boundaries of the Mexican States of Sonora and Sinaloa. UTM Coordinate systemEasting: 675582.80 Northing: 2921170.99, UTM zone: 12 N, Datum: WGS84Geographic location:Latitude: 26.3999, Longitude: -109.2397, Datum: WGS84.--------------------The meteorological instruments are mounted on a tower at approximately 3 meters above the mangrove canopy (mean canopy height = 3.5 meters).

Data proportions:Currently the database has approximately 83% of the data. The remaining 17% of data was lost due to occasional energy failures caused by storms and cloudiness. Missing periods are during the summer period 0f 2018 and from December 13, 2018 to February 2, 2019.--The sampling of the signals from these sensors is every 30 s and the averages are stored in a CR6 data logger (Campbell Scientific, Utah).
