Description
The set consists of 5 files that constitute the main calculations of ammonia emissions over Europe for the years 2013-2020.
The detailed description of variables follows:
1) PriorEmission.nc
- Pall: tensor of the size 240 x 200 x 12 x 8 (lat x lon x months x years) with ammonia prior emissions used in the study [ng/m2/s]
2) PosteriorEmission.nc
- Xall: tensor of the size 240 x 200 x 12 x 8 (lat x lon x months x years) with ammonia posterior emissions [ng/m2/s]
3) UncertaintyEmission.nc
- Uall: tensor of the size 240 x 200 x 12 x 8 (lat x lon x months x years) with uncertainty of posterior emissions [ng/m2/s]
4) stations_vmodVSobs.mat
- st_list: list of stations identifiers, 53 stations in total
- st_coord: stations coordinates [lot,lat]
- st_OBSdays: matrix of the size 53 x (366*8) with observations in daily resolution [ug/m3]
- st_ind_obs: logical matrix of the size 53 x (366*8) with indicators when each station provides observation (1) and when not (0)
- st_prior_vmod_days: matrix of the size 53 x (366*8) with calculated concentrations using model with prior emission [ug/m3]- st_post_vmod_days: matrix of the size 53 x (366*8) with calculated concentrations using model with posterior emission [ug/m3]
- st_prior1_vmod_days: same as st_prior_vmod_days for EC6G4 prior
- st_prior2_vmod_days: same as st_prior_vmod_days for EGG prior
- st_prior3_vmod_days: same as st_prior_vmod_days for NE prior
- st_prior4_vmod_days: same as st_prior_vmod_days for VD prior
