 BDSNP Module for Improved Soil NO Emission Estimates for CMAQ Model, Conterminous USA

简介

该数据集是一个用于改善CMAQ模型中土壤氮氧化物（NO）排放估计的BDSNP模块，涵盖了美国本土的范围。该数据集提供了详细的土壤氮氧化物排放估计，有助于提高对大气中NO浓度和分布的预测精度。

数据集包括土壤类型、土壤pH值、土壤含水量、土壤温度等因素，这些因素对土壤中NO的生成和释放起着重要作用。通过将这些因素结合到CMAQ模型中，可以更准确地模拟土壤中NO的排放过程，从而提高模型对大气中NO浓度的预测精度。
