LON_LAT_TIME_STRING(longitude, latitude, time, time_axis, string) Generate names based on longitude,latitude,time,and a string. For instance, profile data at a set of longitude, latitude stations with data at particular times may need labels for each station.
|
Arguments: |
longitude |
longitude value(s). They will be translated to the range (0,360) |
|
latitude |
latitude values(s). Positive values will be labeled N, negative ones S |
|
|
time |
Numeric time coordinates |
|
|
tim_eaxis |
A variable on the time axis to use in translating time coordinates to time strings |
|
|
string |
A label to start the strings |
|

Result Axes: |
X |
Inherited from longitude, latitude and time arguments |
|
Y |

Example:
yes? ! Longitudes are translated to 0:360 range
yes? let lon = {-172.44, 210.01, -19.5}
yes? ! latitudes are labeled N or S
yes? let lat = {3.12, 4.9, -15.03}
yes? ! Time steps are interpreted in terms of a time axis
yes? let time = {1,2,3}
yes? define axis/t=1-jan-2001:31-jan-2001:1/units=days/t0=1-jan-2001 taxis
yes? let tt = t[gt=taxis]
yes? list lon_lat_time_string(lon, lat, time, tt, "station")
