AirMOSS: L4 Daily Modeled Net Ecosystem Exchange (NEE), AirMOSS sites, 2012-2014

This data set provides Level 4 daily estimates of Net Ecosystem Exchange (NEE) of CO2 at a spatial resolution of 30 arc-seconds (~1 km) for seven of the sites covered by the Airborne Microwave Observatory of Subcanopy and Subsurface (AirMOSS) flights, each site spanning ~2500 km2. The daily NEE estimates are generally available from October 2012 through October 2014, although the exact time ranges vary by site. The AirMOSS L4 daily NEE were produced by the Ecosystem Demography Biosphere Model (ED2) augmented by the AirMOSS-derived L2/3 root zone soil moisture data as an additional input. The AirMOSS soil moisture data were used to estimate the sensitivity of carbon fluxes to soil moisture and to diagnose and improve estimation and prediction of NEE by constraining the model's predictions of soil moisture and its impact on above- and below-ground fluxes.

本数据集提供了亚地表及地表下微波观测系统（AirMOSS）覆盖的七个站点在30弧秒（约1公里）空间分辨率下，净生态系统交换（NEE）的每日四级估计值，每个站点覆盖约2500平方公里。每日NEE估计值通常从2012年10月持续至2014年10月，但具体时间段因站点而异。AirMOSS四级每日NEE由生态系统生物地理模型（ED2）生成，并辅以AirMOSS衍生的L2/3根区土壤湿度数据作为额外输入。AirMOSS土壤湿度数据被用于估计碳通量对土壤湿度的敏感性，并通过对模型预测的土壤湿度及其对地上和地下通量的影响进行约束，以诊断并优化NEE的估计和预测。
