Bulk/wet deposition of trace metals to rural, industrial, and urban areas in the Yangtze River Delta, China.

The bulk depositions of trace metals to three land uses in the Yangtze River Delta are investigated based on the collected 154 precipitation samples from August 2015 to May 2017. The volume-weighted mean (VWM) concentrations of Ni, Cu, Zn, Cd, and Pb were 13.28, 5.

Long-term trends in NO columns related to economic developments and air quality policies from 1997 to 2016 in China.

This study detected the long-term trends in NO concentrations in China from 1997 to 2016 based on the NO columns from GOME, SCIAMACHY, and GOME-2A. Both differences in the time-overlapped NO columns from GOME vs. SCIAMACHAY and SCIAMACHAY vs.

Dry Particulate Nitrate Deposition in China.

A limited number of ground measurements of dry particulate nitrate deposition (NO) makes it difficult and challenging to fully know the status of the spatial and temporal variations of dry NO depositions over China. This study tries to expand the ground measurements of NO concentrations at monitoring sites to a national scale, based on the Ozone Monitoring Instrument (OMI) NO columns, NO profiles from an atmospheric chemistry transport model (Model for Ozone and Related chemical Tracers, version 4, MOZART-4) and monitor-based sources, and then estimates the NO depositions on a regional scale based on an inferred model. The ground NO concentrations were first derived from NO columns and the NO profiles, and then the ground NO concentrations were derived from the ground NO concentrations and the relationship between NO and NO based on Chinese Nationwide Nitrogen Deposition Monitoring Network (NNDMN).
