Ucluelet, Vancouver Island
A few of you have asked what "gribs" are. GRIB is short for GRIdded Binary, or the encoding used for meteorological data. GRIB files are computer-generated forecast files from NCEP/NOAA. We are able to specify a zone or box by latitude and longitude, the grid-spacing in degrees, the forecast times (24, 48, .. hours) and parameters. Parameters include mean sea-level pressure, wind for the gradient surface (10-meter), 500mb height, sea-surface temperature, air temperature (2M altitude) and wave-height. You can also indicate what time you want the data and for how many days you want to get the forecast.
So currently we are requesting data for 49 N 130 W, to 42 N 123W, .5 degree grid-spacing, forecast times of 24, 48, 72, 96, 120 (5 day look ahead), sea-level pressure and winds for the gradient surface and we want to get a forecast every day for now until Sept. 5. We have a program that allows us to view this data graphically on a very crude map but sufficient for us to make a decision whether to continue or to wait for a better weather window.

No worries,
