This project presents a wind sector method and methane inversion over the Arctic to analyse emissions and trends. Found at *Paper DOI*.
Data for each site can be found as follows:
- Barrow, Alaska (BRW): from NOAA GML https://gml.noaa.gov/ccgg/trends_ch4/
- Ambarchik, Russia (AMB): on the Max Planck data sharing platform, https://keeper.mpdl.mpg.de/d/e28989e7a8204b56a49d/
- Cape Baranova, Russia (CBR): From FMI, https://fmi.b2share.csc.fi/
- Tiksi, Russia, (TIK): CH4_tik_surface-insitu_fmi_data1 at WDCGG, https://gaw.kishou.go.jp/
Inversion code can be found in the following repository under the branch name acrg_arctic: https://github.com/ACRG-Bristol/acrg/tree/acrg_arctic
The zip file contains an the data and inputs needed for the Barrow inversion (footprints, priors, basis functions etc.)...
