NSMP first generation SEED metadata available at the NCEDC

The NCEDC has completed the first generation of SEED metadata for instrumentation operated by the USGS National Strong Motion Project. The response information is available in various standard formats. Metadata is present for the history of each channel back to the installation of digitally recording equipment. It required careful assignment of SEED location codes to all NSMP channels to differentiate similar channels in structures. It also required review of historical records to assign serial numbers to all sensors and dataloggers. Unfortunately, sensitivities and response information are not known for some analog dataloggers, such as Kinemetrics SMA-1 recorders. The NSMP will continue efforts to document the response of historic stations, and the NCEDC will update response information to reflect changes in currently operating stations as received.
