Open Source IDL Earth Sciences Software

OVATION Prime is a seasonal model of the diffuse, monoenergetic, proton, and wave aurora. The OVATION Prime model is written in IDL and was developed at the Johns Hopkins Applied Physics Laboratory (JHU-APL) by Patrick Newell and co-workers. This current version includes updates to the retrospective and real time components, several efficiency enhancements and a user configuration as implemented by Rob Redmon and Janet Machol of NOAA. This is a community model. Users are invited to suggest and provide improvements. Documentation includes a model description and instructions for running the software. The README is available here: http://sourceforge.net/p/ovation-prime/code/HEAD/tree/trunk/README.pdf?format=raw A web interface for running the model for historical periods is available here: http://sd-www.jhuapl.edu/Aurora/ovation_prime/prime_display.html Realtime versions are running here: http://www.ngdc.noaa.gov/stp/ovation_prime/ http://www.swpc.noaa.gov/ovation/

* Please check latest update on https://github.com/igps-ftk/iGPS A tool written in Interactive Data Language (IDL), for processing and analyzing daily continuous GPS position time series. It can read time series in various formats, detect outliers, remove abnormal observation spans, find jumps, extract common-mode components(CMC), etc.

RAT is a software for advanced image processing of SAR (Synthetic Aperture Radar) remote sensing data.

The Airborne Data Processing and Analysis (ADPAA) package is an open-source software package containing a collection of programs and scripts to process and analyze data from in-situ instruments deployed on airborne platforms. The ADPAA package was started to process data on the North Dakota Citation Research Aircraft but has been used to process data on many airborne platforms. The software methodology used in ADPAA is provided in the peer-review publication: Delene, D. J., Airborne Data Processing and Analysis Software Package, Earth Science Informatics, 4(1), 29-44, 2011, URL: http://dx.doi.org/10.1007/s12145-010-0061-4, DOI: 10.1007/s12145-010-0061-4.

Provides an API, which enables the Interactive Data Language (IDL) user (and developer) to incorporate Space Weather data and metadata resources from the Space Physics Interactive Data Resource (SPIDR) directly into an IDL application. Examples included.

ESML is an interchange technology that utilizes external metadata to allow applications to plug and play seamlessly with Earth Science specific datasets in heterogeneous formats.

APEX Tools is a collection of utilities used in conjunction with the processing of airborne hyperspectral data developed for the ESA-Prodex supported Airborne Prism EXperiment (APEX).
