UNRESP FORECASING

Overview

DOI
Description:

UNRESP is a research project working on building resilience to an environmental pollution hazard caused by persistent volcanic emissions. The volcanic emissions are termed vumo.

UNRESP is working on Masaya volcano in Nicaragua, one of the biggest volcanic polluters in the world. Very little is known about the dispersion and levels of the air pollution caused by the vumo, and there no established procedures for communicating the vumo hazard between the local authorities and the public.

CEMAC Role

Summary - Create whole package forecasting tool for valcanic emissions - Main Tool - CALPUFF

FORECASING MODEL

Setting a constant point source emmission of Sulphides and Sulphates from Masaya Volcano, daily NAM Data is used to drive a light weight dispersion model (CALPUFF) to forecast over the next 48 hours qualitiative concentraions of SO2 and SO4. The idea beign this could be combined or contrained with overservational data and ran in a matter of minutes to give a quick rough estimates of air quality for the following day

Portability and documentation

This tool has been designed to work on any linux or Mac OS (requires bash, fortran and python) and to work seemlessly to install compile and run the model as well as vizualize the output.

We have tested running this set up on a variety of different machines accross the world with success, running the model set up with minimal effort.

The end goal is to use this a INITER in Nicaragua to allow local volcanologists to use this as a suplimentary tool.

A full repository of code and information is hosted on github .

Vizualization

Along side the modelling code are a set of phython tools to autmatically generate images and animations of the concentraion field for each day. These can also be used as stand alone tools and have been used by our colleauges with ease.

A simple html and javascript framework to host or simply browse the images is also provided and can be launched in its entirety on any web server even a simple http python server.
