Deposition maps of reactive nitrogen over East Asia and Southeast Asia for 2000-2020

This dataset provides the mappings of reactive nitrogen deposition for East Asia and Southeast Asia for 2000-2020 at 0.25°´0.25° resolution. We developed the relationship between site-measured nitrogen deposition and emissions, meteorological and geographical information via an ensemble machine learning approach.  The accuracies of the product were validated by ten-fold cross-validation and independent tests, which suggested a reasonable mean correlation coefficient (0.77).

This dataset contains the following files:

(1) A Readme file;

(2) The "grid.xlsx" defines the 0.25° × 0.25° spatial grid system.

(3) The "Ddrynoy.xlsx", "Ddrynhx.xlsx", "Dwetnoy.xlsx" and "Dwetnhx.xlsx" files include the monthly accumulated wet deposition (Dwet) and dry deposition (Ddry) of NOy and NHx for the years 2000, 2005, 2010, 2015, and 2020. 

(4) The "annual.xlsx" file  contains the annual accumulated wet deposition (Dwet) and dry deposition (Ddry) of NOy and NHx for the years 2000, 2005, 2010, 2015, and 2020
