Using R to analyze GEOS-Chem data
On this page we include a tutorial about how to use the R programming language to analyze GEOS-Chem data.

I have prepared a tutorial for using R to analyze GEOS-Chem and atmospheric data in the package:
with the tutorial R script file and test data:
R_Intro_for_Atmos_Sci.R PM25_met_Ohio_201007.txt PM25_T_daily_US_201007.RData
and an introductory guide to R for MATLAB users:
I have also written many R functions suitable for analyzing 2D and 3D GEOS-Chem, EPA and meteorological data in these source files:
get_geo.R (for spatial analysis and visualization: interpolation, regridding, mapping, etc.) get_met.R (for dealing with time series and meteorological data) get_stat.R (for general statistical and mathematical methods) get_EPA.R (for handling EPA air quality data)
The files include detailed instructions for each function. They can be used by sourcing in the R environment:
These functions will be revised and updated from time to time. Feel free to download and use!
