Dataset description

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) 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 80 km (update of VolcDB1_3D). This version contains the factors of Brühl et al. (2018) for MIPAS included in the ascii-file with the integrals and which were missing in Version 2 (SSIRC_2). 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 210 hPa), 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)

Frequently Asked Questions

Some basic informations about API Store ®.

Operation and development of APIs are currently fully funded by company Apitalks and its usage is for free.
Yes, you can.
All important information such as time of last update, license and other information are in response of each API call.
In case of major update that would not be compatible with previous version of API, we keep for 30 days both versions so you will have enough time to transfer to new version. We will inform you about the changes in advance by e-mail.
