Hi all,I am new to IDV but it looks like a powerful tool. I want to plot aircraft track data which come in netCDF format. However, IDV is unable to read in the current netcdf file I have. Can someone point me to the correct format. At the moment the netcdf file looks something like this:
dimensions:
data_point = UNLIMITED ; // (28980 currently)
sps01 = 1 ;
variables:
int Time(data_point) ;
Time:long_name = "time of measurement" ;
Time:units = "seconds since 2011-04-04 00:00:00 +0000" ;
Time:_FillValue = -1 ;
Time:standard_name = "time" ;
float IAS_RVSM(data_point, sps01) ;
IAS_RVSM:long_name = "Indicated air speed from the
aircraft RVSM (air data) system. " ;
IAS_RVSM:units = "m s-1 " ;
IAS_RVSM:_FillValue = -9999.f ;
IAS_RVSM:Frequency = 1s ;
IAS_RVSM:Number = 516s ;
byte IAS_RVSM_FLAG(data_point, sps01) ;
IAS_RVSM_FLAG:long_name = "Flag for Indicated air speed
from the aircraft RVSM (air data) system. " ;
IAS_RVSM_FLAG:units = 1s ;
IAS_RVSM_FLAG:_FillValue = -1b ;
IAS_RVSM_FLAG:Frequency = 1s ;
float TAS_RVSM(data_point, sps01) ;
TAS_RVSM:long_name = "True air speed from the aircraft
RVSM (air data) system and deiced temperature. " ;
TAS_RVSM:units = "m s-1 " ;
TAS_RVSM:_FillValue = -9999.f ;
TAS_RVSM:Frequency = 1s ;
TAS_RVSM:Number = 517s ;
TAS_RVSM:standard_name = "platform_speed_wrt_air" ;
byte TAS_RVSM_FLAG(data_point, sps01) ;
TAS_RVSM_FLAG:long_name = "Flag for True air speed from
the aircraft RVSM (air data) system and deiced temperature. " ;
TAS_RVSM_FLAG:units = 1s ;
TAS_RVSM_FLAG:_FillValue = -1b ;
TAS_RVSM_FLAG:Frequency = 1s ;
float TAT_DI_R(data_point, sps01) ;
TAT_DI_R:long_name = "True air temperature from the
Rosemount deiced temperature sensor. " ;
TAT_DI_R:units = "degK " ;
TAT_DI_R:_FillValue = -9999.f ;
TAT_DI_R:Frequency = 1s ;
TAT_DI_R:Number = 520s ;
TAT_DI_R:standard_name = "air_temperature" ;
....
Any help is much appreciated.
Best wishes,
Sebastian
