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。

摘要

Spatial Coverage: CMAQ model domain for Continental United States and portions of northern Mexico and southern Canada

Spatial Resolution: 12- by 12-km grid

Temporal Coverage: Input fertilizer data: 20110101 - 20120101; Outputs: 20110621 - 20110622

Temporal Resolution: Hourly

Study Area:

Site	Westernmost Longitude	Easternmost Longitude	Northernmost Latitude	Southernmost Latitude
CONUS	-129.79	-65.00	51.76	22.75

Table 1. Fortran source files

Filename	Description
BDSNP_MOD_EPIC.F	Gives soil NO parameterization as given by Hudman et al. (2012) with options of enhancement in terms of 'new' soil biome (NLCD40 for 2006) and dynamic fertilizer nitrogen pool from EPIC (Cooter et al., 2012; see Data Acquisition, Materials, and Methods)
canopy_nox_mod.F	Source code for incorporating canopy reduction of soil NO as proposed by Hudman et al. (2012)
cldproc_acm.F and vdiffacm2.F	Two source code files for obtaining total mass of nitrogen per unit area deposited to the ground from the atmosphere through wet (cldproc_acm.F) and dry (vdiffacm2.F) deposition.
tmpbeis.F	Source code to create model-ready biogenic emissions from gridded land use data with emissions inputs in moles/second; in this implementation, tmpbeis.F has been modified to give the option to calculate soil NO emission either from Yienger and Levy (1995) parameterization or from BDSNP (see Data Acquisition, Materials, and Methods)
