makefile 1kB Makefile
C source code 9kB getp3rec.c Read a P-3 record from standard input that has been written to disk using rtape with the record headers enabled. Return the record size in shorts.
C source code 12kB hrdair.c Translate hrd in situ aircraft tape data to Candis format. Assumes that tape has been read by the rtape utility. This is the second version of this program. David Leon pioneered the first version. Information from Dave Jorgensen used to decode GPS data in type 4 records.
C source code 2kB hrdasciitrans.c This makes a simple translation of the 2001 ascii data table from NOAA 43 in EPIC2001 to a form that cdftable can read.
C source code 29kB hrdrad.c Convert HRD P-3 data to Candis format.
C source code 5kB hrdrawair.c Translate Dave Jorgensen's ascii file of P-3 slow tape to Candis format.
C source code 4kB hrdrawair2.c Translate Dave Jorgensen's ascii file of P-3 slow tape to Candis format.
C source code 2kB rawget.c Get a 1 sec record from P-3 slow tape data file created by Dave Jorgensen for quick look purposes. Returns a null pointer at end-of-file.
C source code 1kB rawget.h include file that defines structure of single time P-3 aircraft slow tape -- data in ascii form from Dave Jorgensen
C source code 2kB rawget2.c Get a 1 sec record from P-3 slow tape data file created by Dave Jorgensen for quick look purposes. Returns a null pointer at end-of-file.
C source code 1kB rawget2.h include file that defines structure of single time P-3 aircraft slow tape -- data in ascii form from Dave Jorgensen
21kB rdrst.f Subroutine to read OAO standard tapes and Return 1 sec of data
text 7kB rec_type4_43.txt
text 5kB rec_type5.txt
C source code 1kB rertape.c This inserts the rtape ascii block sizes in an HRD P-3 insitu file. This assumes that the input block sizes are 34, 808, 384, 4440, 2120, 4440, 2120, ... bytes, etc.
2kB rertape.c.test
29B system
C source code 3kB unfoldit.c do a very simple unfolding scheme --
  1. aircraft velocity is removed
  2. discontinuities greater than vinter/2 are unfolded
  3. each good data segment has vinter added to or subtracted from it until the mean is as close as possible to the wind component along the ray
