Description: 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 system Easting: 675582.80 Northing: 2921170.99, UTM zone: 12 N, Datum: WGS84 Geographic 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).

Description: Objective: The objective of this database is to identify the phenological seasonality of the mangrove along the southern coast of the state of Sonora, in northwestern Mexico. Especially with the use of the Normalized Difference Vegetation Index (NDVI) obtained from satellite information. This dataset is part of a larger project entitled "Environmental Controls on the temporal evolution of Energy and CO2 fluxes on an Arid Mangrove of Northwestern Mexico". Both the project are managed by the Instituto Tecnológico de Sonora (ITSON) and funded by the National Laboratory of Coastal Resilience (LANRESC) and the National Council of Science and Technology (CONACYT). --- Study site The study site is found at the coastal intertidal zone of the northern edge of Mazocarit Island, approximately 400 meters east of the Navopatia Field Station, both located in northwestern state of Sonora, México.

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. The navopatia meteorological station is in the northern tip of the Mazocarit Island characterized by the presence of red mangrove (Rhizophora mangle) with the following location: UTM Coordinate system Easting: 675582.80 Northing: 2921170.99, UTM zone: 12 N, Datum: WGS84 Geographic location: Latitude: 26.3999, Longitude: -109.2397, Datum: WGS84 --- Data: Normalized Difference Vegetation Index (NDVI) was generated from band 4 (664.5 nm) and band 8 (NIR, 835.1 nm) of Sentinel -2 MSI (MultiSpectral Instrument, Level-1C) as part of the COPERNICUS / S2_SR data collection. Image processing and time series extraction with Google Earth Engine (GEE, https://earthengine.google.com). A total of 104 low-cloud cover (〈 5 % cloud cover) images were processed to generate the NDVI time series by type of mangrove. In addition, data contamination was eliminated using the method of moving averages with 12 days. The NDVI data were extracted from two different regions of interest (ROI) defined by the dominant mangrove species that covers the surface.

Description: Objective: ----- The objective of this database is to measure and identify the seasonal variation of atmospheric exchange fluxes of carbon, water, and energy in a mangrove site in the southern coastal line of the Northwestern Mexican State of Sonora. This fluxes dataset is part of a larger project entitled "Environmental Controls on the temporal evolution of Energy and CO~2~ fluxes on an Arid Mangrove of Northwestern Mexico". Both the project and the eddy covariance (EC) station are managed and operated by the Instituto Tecnológico de Sonora (ITSON) and funded by the National Laboratory of Coastal Resilience (LANRESC) and the National Council of Science and Technology (CONACYT). ------------------ Study site ----- The study site is found at the coastal intertidal zone of the northern edge of Mazocarit Island, approximately 400 meters east of the Navopatia Field Station, both located in northwestern state of Sonora, México.

The eddy covariance system are installed in an 8 meter height tower on 6.5 meters above the mangrove canopy (mean canopy height = 5 meters), with a sampling rate 10 Hz. ------------------ Data ----- Sensible heat (H), latent heat (λE), net exchange ecosystem (NEE) and Bowen relation data. Processed under the protocols of Burba & Anderson (2010) with corrections for density variations caused by temperature, precipitation, and air humidity (Webb et al., 1980). And a quality control of the flows under the system of Mauder and Foken (2004). The missing data in the time series of energy fluxes and CO2 (NEE) corresponded to 42% of the entire data set and were completed with the methods developed by Reichstein et al. (2005) and Falge et al. (2001) and executed using the R-based processing tool REddyProc (Wutzler et al., 2018). This tool was developed by the Department of Biogeochemical Integration of the Max Planck Institute for Biogeochemistry and performs the filling of gap data considering both the covariation of vertical flows with meteorological variables and their temporal autocorrelation. Finally, flows below a friction velocity threshold (u *) of 0.29 m s-1 were discarded for the entire data set.
