SOLFEO biogenic isoprene emission estimates over South America.

* Introduction

This document discusses the biogenic isoprene emission estimates over South America.
Available at https://emissions.aeronomie.be/index.php/tropomi-based/isoprene-sa


The biogenic isoprene emission estimates are derived using the adjoint of 
the MAGRITTE chemistry-transport model Müller et al., 2019) 
constrained by tropospheric HCHO column densities from the TROPOMI satellite 
instrument (De Smedt et al. 2018). HCHO data are publicly available via 
http://www.tropomi.eu/data-products/formaldehyde. The a priori isoprene emissions 
(MEGANv2-ECMWF) are taken from Stavrakou et al. (2013).


* The file format and contents

The data are provided in NetCDF files for the year 2018. The 
values are in kg / (gridcell+ACo- month) in a regular grid with a 0.5 by 0.5 
degree resolution. Logitudes range from -85 to -32
and Latituses range from 15 to -34.

* Additional information

The dataset is described in detail in the final report of the SOLFEO project:
