Scripts for processing IGETS data: **igetsDataTools**
=====================================================
This repository contains **Matlab/Octave** scripts and functions related to loading/writing/processing of gravimeter data stored in **International Geodynamics and
Earth Tide Service** ([IGETS](http://igets.u-strasbg.fr/data_products.php)) database.  
### Dependency
* To run any script, download the [hydroGravityLib](https://github.com/emenems/hydroGravityLib) (Matlab/Octave HydroGravity Library) and adjust the paths in the script accordingly
* All scripts should work with both, Matlab and Octave, although the loading of one second monthly data in Octave takes lot of time :-(  
* Scripts tested using iGrav006 gravimeter data

### Scripts and Functions
* `igets_set_and_run.m`: **main script** containing all settings. Run this script to call other processing functions
* `igets_raw_to_ggp.m`: conversion of 1 second iGrav [TSoft](http://seismologie.oma.be/en/downloads/tsoft) files to ggp/igets data format/database, i.e., convert daily data to monthly files  
* `igets_sec_to_min.m`: filter and re-sample/decimate the created or downloaded monthly ggp/igets data to 1 minute data
* `igets_min_to_hour_res.m`: filter and re-sample the 1 minute data to hourly gravity residuals
* `igets_export_data.m`: load + stack one second/minute/hour data and save the whole time series into one file (ggp/tsf/mat format)  
* `igets_import_data.m`: import data stored in other formats (e.g. tsf or mat) to IGETS database. For example: use to convert precipitation data

### Auxiliary files
Besides the IGETS data, some auxiliary files are needed. The `data` folder contains examples of such files:
* modified filter files: `g1s1md.gwr` (1 second to 1 minute) and `g1m1h.nlf` (1 minute to 1 hour). Always use (modified) filters recommended by IGETS!
* `tides_file_example.tsf`: tides time series used when computing gravity residuals
* `correction_file_example.txt`: correction file used in to remove anomalous time intervals (set to NaN), gaps (linear interpolation) and to remove steps
