This workflow tool was originally developed by students of the Applied Concepts in Cyberinfrastructure (ACIC) in 2014 at the University of Arizona. The semester long project resulted in a parallel workflow tool run on the University's high performance computing (HPC) system.
The project then received an Extreme Science and Engineering Discovery Environment (XSEDE) Extended Collaborative Support (ECS) start-up allocation. The results of that effort were described in Swetnam et al. (2016). The start-up allocation was followed by a research allocation on SDSC Comet and the Open Science Grid. A publically available tool using the workflow is deployed on OpenTopography.org.
The workflow is containerized and can be run on local machines (laptops, desktops, clusters), cloud, or HPC/HTC using Singularity.
The student's called their solar radiation project Sol, and we continue to use that naming scheme here. The Sol program calculates daily and monthly global irradiation and hours of sun.
Effective Energy and Mass Transfer (EEMT) Rasmussen et al. (2015) is a representation of environmental energy and mass transfer doing work on the Earth's 'critical zone'. To learn more about the critical zone, visit the NSF Critical Zone Observatories.
This Github repository consists of (1) an Opal2 virtual machine deployment script for running jobs on the OpenTopography, (2) a Singularity file which is hosted on Singularity Hub, (3) provisioning scripts for running the workflow on Jetstream and the Open Science Grid, (4) scripts for running Sol with Makeflow, and (5) scripts for calculating EEMT with Makeflow.
On a small VM or workstation.
Pull this repository:
git clone https://cyverse-gis/eemt
Start the master:
./eemt/sol/run-master eemt/sol/examples/mcn_10m.tif
Start the worker:
./eemt/sol/run-worker EEMT
Download the OSGEO GIS Singularity container to run locally.
singularity pull --name osgeo.simg shub://tyson-swetnam/osgeo-singularity
then
singularity exec osgeo.simg qgis
or
singularity exec shub://tyson-swetnam/osgeo-singularity qgis
Climate data are available from numerous organizations, e.g. Daymet, WorldClim, Chelsa. These data are used in the EEMT calculation.
