ROVER is a command line tool to robustly retrieve geophysical timeseries data from data centers such as EarthScope. It builds an associated index for downloaded data to generate a local repository. ROVER compares a built local index to timeseries availability information provided by the datacenter. This enables a local archive to remain synchronized with a remote data center.
ROVER is a command-line tool that requires Python 3.8 or a later. We suggest installing Miniconda 3 (or the full Anaconda if you wish) for the best results.
ROVER requires the C language program mseedindex be available in the user’s path. A C compiler and the make program are required to build mseedindex. ROVER and mseedindex may be downloaded and compiled simultaneously using pip:
pip install rover
You should now be able to type rover --version to see if it was successfully installed.
Initialize a data repository, which creates the datarepo directory, and change into the new directory:
rover init-repository datarepo
cd datarepo
Create a request file named request.txt containing:
IU ANMO * LHZ 2012-01-01T00:00:00 2012-02-01T00:00:00
TA MSTX -- BH? 2012-01-01T00:00:00 2012-02-01T00:00:00
Run the process rover retrieve to fetch these data:
rover retrieve request.txt
list-summary prints the retrieved data from the earliest to the latest timespans:
rover list-summary
IU_ANMO_00_LHZ 2012-01-01T00:00:00.069500 2012-01-31T23:59:59.069500
IU_ANMO_10_LHZ 2012-01-01T00:00:00.069500 2012-01-31T23:59:59.069500
TA_MSTX__BHE 2012-01-01T00:00:00.000000 2012-01-31T23:59:59.975000
TA_MSTX__BHN 2012-01-01T00:00:00.000000 2012-01-31T23:59:59.975000
TA_MSTX__BHZ 2012-01-01T00:00:00.000000 2012-01-31T23:59:59.975000
Retrieved files are miniSEED format containing day lengths of station data. The files are saved with the path structure:
<datarepo>/data/<network>/<year>/<day>/<station>.<network>.<year>.<day>
ROVER has built-in help. The command rover help prints a ROVER introduction to the terminal.
There are many more options available in ROVER including; the ability to send emails that monitor
ROVER request and subscriptions (see the --email option), view listings of contiguous traces (via the rover list-index join command), or view the status of a long-running download using a web browser (by default at http://localhost:8000/).rover help help prints a list of commands available in the ROVER code suite.
ROVER is configurable via the rover.config file or by using the command line. Type rover -h to see the configuration parameters that are adjustable using the command line.
For more detailed examples, see more example commands to download data and example commands to manage and maintain the local repository.
