[lat/long]

could well be, the readme for the script says:

"lat and long will be in the range -90 to 90 degrees lat and 0 to 359 degrees long. Longitude in GRIB files is 0 to 359 east. If you have degrees in longitude west you will need to convert it first. If lat or long is out of range for the current file an error will be set ( see getError() )."

so its 359 degrees, maybe then if i was looking for 50.12N -3.14W this would be 50.12N 355.88E?

pretty confusing huh!

[lat/long]

Hi,

I am using a script to get some weather data from a grib file, lets say for example that the lattitude is 50 and the longitude is -3. The script I'm using works with longitude from 0 to 360 therefor eno minus figures. it says if i have a west degree i need to convert it to east. I don't understand this does it mean -3 west is 183 east?

Thanks for your help

Thanks for the comment but i had a look there and its just charts for free, i might think about buying some data but i thought it was free from places like noaa? i'm just having trouble finding it.

Hi,

Would anyone know a good place to get data for weather prediction, ideally for free. I am a surfer and looking for a place to get data (swell, pressure wind etc) to feed into a model i am making. I have looked around the noaa website a fair bit but its quite hard to navigate around it. any ideas would be very greatly appreciated.

Thank you
