IRISSeismic (version 1.6.6)

getSNCL: Retrieve seismic data from IRIS DMC

Description

The getSNCL() method is a convenience wrapper for the getSNCL() method and returns a Stream object in which individual Traces have been sorted by start time.

Usage

getSNCL(obj, sncl, starttime, endtime, ...)

Value

A new Stream object is returned.

Arguments

obj

IrisClient object

sncl

character string with the SNCL code

starttime

POSIXct class specifying the starttime (GMT)

endtime

POSIXct class specifying the endtime (GMT)

...

optional arguments quality optional character string identifying the quality. IRIS webservices defaults to quality="M". repository optional character string identifying whether to exclusively search primary archive or realtime collection buffers. Acceptable values are "primary" or "realtime". If not specified, IRIS webservices defaults to both repositories. inclusiveEnd optional logical determining whether the endtime is inclusive (default = TRUE) ignoreEpoch optional logical defining behavior when multiple epochs are encountered (default = FALSE)

Details

The SNCL argument should be ordered network-station-location channel, e.g. IU.ANMO.00.LHZ. This argument is split into component parts which are then used in a call to the getSNCL() method.

# Use getSNCL to request data for II.JTS.00.BHZ
starttime <- as.POSIXct("2001-02-28",tz="GMT")
endtime <- as.POSIXct("2001-03-01",tz="GMT")

st <- getSNCL(iris, "II.JTS.00.BHZ",starttime, endtime, quality="M",
              repository="primary",inclusiveEnd=FALSE,ignoreEpoch=TRUE)

# Display structure of trace(s)
