Meteorological Data from a Basin Mangrove in Northwestern Yucatán

Meteorological data from the Ejido de Sisal ecohydrological observatory (MexFlux: MX-Sis ), located at 21.1255°N, 90.0060°W, cover the period from March 18, 2022, to April 20, 2023. The monitored ecosystem is a basin mangrove, where the following species are present: Conocarpus erectus, Avicennia germinans, Rhizophora mangle, and Laguncularia racemosa. The data are reported in local time (UTC−6). The variables included in the dataset are described below: TA: Air temperature in degrees Celsius (°C) P: Atmospheric pressure in Pascals (Pa) RH: Relative humidity in percent (%) VPD: Vapor pressure deficit in Pascals (Pa) Tdew: Dew-point temperature in degrees Celsius (°C) Wind_Speed: Wind speed in meters per second (m/s) Wind_Dir: Wind direction in degrees clockwise from North (°) PAR: Photosynthetically Active Radiation in Watts per square meter (W/m²) RAIN: Accumulated precipitation in millimeters per 30 minutes (mm/30 min) RG: Global radiation in Watts per square meter (W/m²) RN: Net radiation in Watts per square meter (W/m²) SHF: Soil heat flux in Watts per square meter (W/m²) TW: Water surface temperature in degrees Celsius (°C) TS: Canopy temperature in degrees Celsius (°C) WL: Floodwater level relative to the sediment surface in meters (m) Instrumentation The instrument models and installation heights are listed below.
