Abstract
This archive contains new measurements of methanol, ethene, ethyne, and HCN from the CrIS satellite sensor, as well as the code developed for the figures in the following manuscript.
Description
The data is contained in the following files:
- ROCRv2_Methanol_2012to2023.zip: This is an archive containing the methanol retrievals from the ROCRv2 algorithm applied to Suomi-NPP CrIS radiances.
- ROCRv2_Ethene_2012to2023.zip: This is an archive containing the ethene retrievals from the ROCRv2 algorithm applied to Suomi-NPP CrIS radiances.
- ROCRv2_Ethyne_2012to2023.zip: This is an archive containing the ethyne retrievals from the ROCRv2 algorithm applied to Suomi-NPP CrIS radiances.
- ROCRv2_HCN_2012to2023.zip: This is an archive containing the HCN retrievals from the ROCRv2 algorithm applied to Suomi-NPP CrIS radiances.
Each of the above archives contain one file for each year from 2012-2023, with the following variables:
- Column: Monthly mean column densities (molec/cm^2) on a 0.5x0.625 degree grid, of size lat x lon x P90 x month
- lat: center latitude of the data grid
- lon: center longitude of the data grid
- P90: P90 values at which the retrievals were performed (hPa)
This code repository contains subdirectories with the code to recreate each figure in the manuscript. Most routines are written in IDL, apart from two in Matlab and R. The IDL/ folder contains libraries referenced in the IDL routines.
If the code for a particular figure requires preprocessed data as input, it is included in the corresponding subdirectory. If there is no data in the subdirectory, then the code processes the ROCRv2 monthly files described above.
