Greenness Trends and Carbon Stocks of Mangrove Forests Across Mexico, 2001-2015

This dataset provides estimates of greenness trends, above- and belowground carbon stocks, and climate variables of the persistent mangrove forests on the coasts of Mexico (PMFM) at a 1 km resolution from 2001 through 2015. Data are available as one-time estimates or across the temporal range; typically as monthly summaries. One-time estimates of aboveground carbon and soil organic carbon stocks for the PMFM derived from existing sources are provided. Also included are the monthly mean normalized difference vegetation index (NDVI) from MOD13A3 used to derive greenness trends, monthly mean air temperature, and total monthly precipitation from Daymet for 2001-2015 across the PMFM. Other files include the distribution and coverage of PMFM across Mexico. Distributions are provided as four categories of PMFM: (1) Arid mangroves with Surface Water as main input, along the Gulf of California and Pacific Coast (ARsw); (2) humid mangroves with surface water input along the Pacific Coast (HUsw-Pa); (3) humid mangroves with surface water input along the coast of the Gulf of Mexico (HUsw-Gf); (4) humid mangroves with groundwater input along the Gulf of Mexico and Caribbean Sea (HUgw). These data provide a baseline for national monitoring programs, carbon accounting models, and greenness trends in coastal wetlands.

本数据集提供了墨西哥沿海（PMFM）持久性红树林的绿色度趋势、地上及地下碳储量以及气候变量的估计值，时间跨度为2001年至2015年，空间分辨率为1公里。数据以单次估计或时间序列数据形式提供，通常以月度概要的形式呈现。还包括了从现有来源推导出的PMFM地上碳和土壤有机碳储量的单次估计值。此外，还包括了用于推导绿色度趋势的MOD13A3月度平均归一化植被指数（NDVI）、2001-2015年PMFM的月平均气温和总月降水量。其他文件还包括了PMFM在墨西哥的分布和覆盖率。分布数据分为PMFM的四个类别：（1）以地表水为主要输入的干旱红树林，沿加利福尼亚湾和太平洋沿岸（ARsw）；（2）沿太平洋沿岸有地表水输入的湿润红树林（HUsw-Pa）；（3）沿墨西哥湾沿岸有地表水输入的湿润红树林（HUsw-Gf）；（4）沿墨西哥湾和加勒比海的地下水输入的湿润红树林（HUgw）。这些数据为国家级监测计划、碳核算模型和沿海湿地的绿色度趋势提供了基准。
