The VPR coefficients are tabulated in the Supplement for dif ferent types of plume particles (andesite, obsidian, pumice,ice, and water droplets), for both the Mt. Etna and Eyjafjalla j kull volcanoes, and for the Terra and Aqua MODIS instru ments.
Figure shows the VPR procedure flowchart (dashed rect angle). Among the ancillary data, the land sea mask is usu ally available with the radiance data while the operator has todefine the plume mask and possibly the meteorological cloudmask.

The novel VPR procedure described here applies a new at mospheric model for estimating volcanic cloud transmittance(white box, inside the dashed square in Fig. ); the other stepsare unchanged.
In Section the VPR procedure is first described in its key features,namely the plume transmittance model, the ash Re and AOD , andthe SO columnar content estimations.

The ash and SO plume abundance maps are computed using the Volcanic Plume Removal (VPR) proce dure originally applied to MODIS (Moderate Resolution Imaging Spectroradiometer) sensors on board theNASATerra andAqua satellites.
