TError

DOI

TError is a Matlab package designed to quantify the uncertainty of eruption source parameters calculated from tephra deposits. Inputs of the code are a range of field-based, model-based and empirical parameters (i.e., clast diameter, crosswind and downwind ranges, thickness measurement, area of isopach contours, bulk deposit density, empirical constants and wind speed).

TError is a contraction of Tephra and Error. Any bad joke is not intentional.

Repository content

The repository contains the following files:

dep/ Dependencies to the code

Usage

For both TError_sensitivity.m and TError_propagation.m, edit the header of the files and run the script in Matlab.

Output

Upon completion, a folder named OUTPUT containing sub-folders named after the run name are created.
