# VeloDT
[](https://zenodo.org/badge/latestdoi/121383426)
[](https://travis-ci.org/cmeessen/VeloDT)
*VeloDT* contains two C++ implementations of *Vp*- and/or *Vs*-conversions to temperature and/or density valid in the upper mantle.
Vp and Vs converted from PREM (Dziewonski and Anderson, 1981) using the two
different approaches.
## Getting started
Either clone the github repository with
```bash
git clone https://github.com/cmeessen/VeloDT.git
```
or download the [latest release](https://github.com/cmeessen/VeloDT/releases/latest) as source code or binary and extract it somewhere. If you downloaded the source code, you will have to compile the code (see below).
- [**V2RhoT**](./V2RhoT.md) closely follows [Goes et al. (2000)](https://doi.org/10.1029/1999JB900300) to convert vp or
vs to temperature and density assuming a mineral assemblage
- [**V2T**](./V2T.md) implements the method by [Priestley and McKenzie
(2006)](https://doi.org/10.1016/j.epsl.2006.01.008) and converts *Vs* to temperature
- [**T2Rho**](./T2Rho.md) applies the equations of [Goes et al. (2000)](https://doi.org/10.1029/1999JB900300) to compute densities from a given mineral composition, temperature and pressure
Please refer to the original publications for validity and pitfalls of the methods.
A Python implementation of *V2RhoT*, optimized for regularly gridded data, is available [here](https://github.com/cmeessen/VelocityConversion).
### Requirements
The requirements for compilation and running the code are
- [Qt4](https://www.qt.io/download) or later and qmake
- a C++ compiler, e.g. GCC
Requirements for plotting the example:
- [GMT](http://gmt.soest.hawaii.edu/)
- make
### Compiling
Navigate to the base folder `./VeloDT` and execute
```bash
qmake
make
```
This will build the `V2RhoT` and `V2T` executables and put them in the `./VeloDT` folder.
