With present computational capabilities and data volumes entering the Exascale Era, digital twins of the Earth system will be able to mimic the different system components (atmosphere, ocean, land, lithosphere) with unrivaled precision, providing analyses, forecasts, and what if scenarios for natural hazards and resources from their genesis phases and across their temporal and spatial scales. DT-GEO aims at developing a prototype for a digital twin on geophysical extremes including earthquakes, ...

Forecasting the atmospheric dispersal of volcanic products requires accurate input parameters for transport models, including meteorological data and ash/gas emission terms. Such forecasting builds upon three basic ingredients:

1. Meteorological Data. Typically derived from global, regional, or local-scale models, meteorological data drive the transport and deposition of volcanic particles.
2. Transport Models. These models simulate atmospheric dispersal, incorporating processes such as wind ...

Active volcanoes often host settlements in their vicinity, exposing populations to geohazards related to their activity, in particular during unrest phases, when the potential for eruption is higher. Mount Etna is one of the most active volcanoes worldwide, closely monitored by a sophisticated network, and surrounded by several villages and the city of Catania. While the frequent summit activity, characterized by lava fountains and ash-rich plumes, poses a significant hazard to civil aviation, ...

PyCOMPSs DT-LAVA-WF (Lava flow digital twin component DTCV3) run in linux, local laptop experiment test

The DTC-V4 workflow (WF5401) relies on an atmospheric dispersion model to build the relationship between the plume height and SO2 flux (which taken together are called Eruption Source Parameters, or ESPs) and the SO2 ground concentrations. Here we use FALL3D dispersion model, however as the HMC scheme requires many thousands of forward runs we replace it with an Emulator, a function that approximates the model but runs much faster. So far, a simple interpolate-scale-sum emulator that makes use ...

CWL + RO-Crate Workflow Descriptions

This repository stores computational workflows described using the Common Workflow Language (CWL) and enriched with metadata using Research Object Crate (RO-Crate) conforming to the Workflow Run RO-Crate profile.

Each workflow is contained in its own directory (e.g., WF5201, WF6101, ...). Inside each workflow directory you will typically find at least:

• The CWL workflow definition (with the same name as the directory, e.g., WF5201.cwl). ...
