If there are data gaps, we will need to determine whether or not we can retrieve the the data. In some cases, we will need to login to the remote Sparcs and retrieve the day files from that system. And in other cases, we will need to go directly to the Quanterra digitizer to retrieve the data. There will be times when we cannot retrieve the missiing data. Programs such as sdrsplit and qmerge are used to manipulate the data stream further.
Scripts automate the process of retrieving data and later, merging and renaming the data files.
Several tasks are performed daily for each stations' data. For archiving purposes, a complete 24-hour day file is created. If there are any gaps in the data, steps are taken to retrieve the missing gaps, if possible, so as to have the most complete day file as possible. Programs and scripts used to manipulate the SEED data will be discussed in detail. The URL's for BLO, CCM, MPH, PLAL, SIUC, SLM, and UALR follow the same pattern.
