Volcanic SO2 data derived from limb viewing satellites for the lower stratosphere from 1990 to 2019, and from nadir viewing satellites for the troposphere

This directory contains volcanic SO2 data derived from limb viewing satellites for the lower stratosphere from 1990 to 2019. The usage of the data is described in Timmreck et al., (2018), datasets VolcDB1 and VolcDB1_3D. We provide 3D-plumes of observed volume mixing ratio perturbations in the lower stratosphere / upper troposphere typically derived from 10-day periods as nc-file and integrated values of injected SO2 mass with peak latitudes and altitudes as Fortran formatted ascii file (33X,A11,5X,6(I3,1X),I4,1X,5(I3,1X),6(I3,1X),I5,1X,4(I3,1X),I3) for at maximum 6 events at one time. Instead of A11 I2,A4,I5 can be used to read in the components of time.

The data from Jan. 1990 to Jan. 2002 are based on L2-files of SAGE II (V7.0) provided by the NASA DAAC (Thomason et al., 2008). The data from Jul. 2002 to Mar. 2012 use the updated 5-day time series of MIPAS (Hoepfner et al., 2015), supplemented by SO2 derived from GOMOS extinctions (Bingen et al., 2017, with a

corresponding table, scaled for lower resolution). After March 2012 based on OSIRIS (Rieger et al., 2019).

volc_SO2-3D-vmr-perturbation-1990-2019.nc: 3D SO2 for 258 days with eruptions in T63L90 resolution (ECHAM-grid in grid-T63L90.nc). Latitude from South to North, for use with ECHAM please reverse. The levels on the hybrid-grid in the grid files are defined as lev(x,y,z)=hyam(z)+hybm(z)*apsave(x,y), in Pa (apsave annual average of surface pressure or orography), surface to 80km (update of VolcDB1_3D).

volc-so2-inventory.ps: plot of zonal averages of SO2 perturbation at 3 altitudes (gaps not shown, widths of bars have no meaning).

volc-SO2-mass.txt: integrated SO2 mass injected (in kt), SAGE, ENVISAT and OSIRIS period (update of VolcDB1). The volcano names are in the first column, see also http://www.volcano.si.edu (Smithsonian volcano database), Schallock et al. (2021) and SSIRC_1 (doi:10.1594/WDCC/SSIRC_1).

AEROCOM-DIEHL-degassing-volc-SO2.nc: Fluxes from outgassing volcanoes in the troposphere (below 210hPa), taken from AEROCOM (Diehl et al., 2012). Caution, filled with odd climatology after 2009, monthly (subset beginning Jan. 1990).

volc-globalforcing-tropo.nc: EMAC results for instanteneous global radiative radiative forcing by stratospheric aerosol near the tropopause (in W/m2), figure see Schallock et al. (2021)
