Resource: parameter

The parameter resource is used to specify various program parameters that don't really fall into any of the standard resources.  It covers miscellaneous resources.  Often, several parameters need to be specified and these are listed separated by commas.

Common Parameters

Heat index - program: heat

• thi -- print temperature humidity index
• heat -- print heat index
• dew -- table is dewpoint vs temp
• rh -- table is RH vs temp

Message queues - program: loopset, dataset

• to:# -- timeout value in seconds

Radar decoding - program: radcvt

• raw_sum -- use raw summary in SD product rather than deriving it from MDR reports

Raw math - program: rawmath

• miss=# -- value to use for missing reports. This value will be used for any station that does not report.
• noattr -- eliminate plot attributes from output file

Surface decoding - program: sacvt

• time -- include time in output file (WXP ASCII file only-default)
• notime -- don't put time in output file
• range=#:# -- range of times in minutes to include in output file.  The first number is the minutes prior to valid time to accept data.  The second number is the minutes after the valid time to accept data.
• pln -- single line output for decoded printout
• plns -- double line output for decoded printout (default)
• psyn -- use simple synoptic format for decoded printout
• pfull -- multiline output for decoded printout
• all -- save all stations
• dup -- eliminate all duplicate stations, keep corrections as separate reports.
• update -- update existing station with corrections, eliminate duplicates.

Synoptic decoding - program: smcvt

• wmo - save station with its WMO ID (5 digit).
• id - save station with its ICAO ID (4 letter).
• id_enc - save station with its ICAO ID and encode one if missing.

Text data parsing - program: parse

• blank -- stop parsing at a blank line
• 3blank -- stop parsing after 3 blank lines
• dollar -- stop parsing at a dollar sign
• equal -- stop parsing on a trailing equals sign
• line[=lines] -- stop parsing after set number of lines (default 1)
• first -- print only the first occurrence
• last -- print only the last occurrence
• cont -- keep file open to search for new products as they arrive
• hdr -- print just the headers
• prod -- print just the product
• hdr+prod -- print the header and the product

Surface data parsing - program: sa_parse

• dec -- decode raw surface data prior to output
• raw -- print raw undecoded surface data
• pln -- single line output for decoded printout (default)
• plns -- double line output for decoded printout
• psyn -- use simple synoptic format for decoded printout
• pfull -- multiline output for decoded printout
• pvar -- uses variable resource to create table of station data
• blank -- display stations not reporting
• city -- use a city database to sort station data into a particular order
• cvt -- parse a decoded file rather than a raw file
• header-1 -- print a column header only once
• header-e -- print a column header for every station

SHEF processing - program: shefcvt

• date:date -- specifies the date string to output in the raw file

GRIB querying - program: griblook

• nodhr - Don't use header file for quick lookup
• usehdr - Use a header file for quick lookup
• max_bad=limit - Specifies limit of bad values that causes rest of GRIB decoding to stop

Wind chill - program: wchill

• wcval -- print wind chill value (W/m2)
• wctemp -- print wind chill temperature
