.SH NAME 
3
.B timeres - change the time resolution of a trajectory

.SH SYNOPSIS 
5
.B timeres
6
.I inpfile
7
.I outfile
8
.I -[h|min] value
9
.I [-cubic|-linear]
10
.SH DESCRIPTION
11
Change the time resolution of an input trajectory file "inpfile" through interpolation and write a new trajectory file "outfile". The new time resolution "value" is given either in hours "-h" or in minutes "-min". The interpolation is performed on the trajectory file either in linear mode ("-linear") or in cubic spline mode ("-cubic"). The default is "-cubic".

.SH PARAMETERS
13
.TP 15
14
.I inpfile
15
input trajectory file
16
.TP 15
17
.I outfile
18
output trajectory file (can be the same as inpfile).
19
.TP 15
20
.I -h value
21
new time resolution in hours (e.g. "-h 1").
22
.TP 15
23
.I -min value
24
new time resolution in minutes (e.g. "-min 15").
25
.TP 15
26
.I -linear
27
linear interpolation between two trajectory times; note that this mode conserves the sign between two trajectory times - possibly of important for specific humidity, relative humidity,...
28
.TP 15
29
.I -linear
30
subic spline interpolation between two trajectory times; note that this mode conserves can change the sign between two trajectory times!
31
.SH EXAMPLES
32
.TP 5
33
.B [1] timeres trafile trafile -min 15 -linear
34
changes the time resolution to 15 minutes, using linear interpolation, and overwrites the old trajectory file.
