grib@seaweather.net is an automated email system developed by Weather Routing, Inc. for retrieving GRIB data.

You can send an email to this address with subject \"grib\" and \"instructions\" in the body of the email to receive this message in your inbox at any time.

NOTES:

1. You must send your request from the e-mail address you registered your SeaWeather account with, or the \"Vessel Email\" address that was optionally specified during registration, or be authorized by WRI to use this system.

2. Please be aware of file size restrictions for your email system. Keep in mind that our GRIB data is 0.5 degree resolution, and the larger the lat/lon range and more forecast hours/parameters requested, the larger the resultant GRIB file will be. The system will not send GRIB files that are larger than 1 MB (1 megabyte or 1024 Kilobytes)

3. Need a GRIB viewer? WRI recommends the FREE Unidata Integrated Data Viewer (IDV) located here: http://www.unidata.ucar.edu/software/idv/

INSTRUCTIONS:

The GRIB request system looks for specific parameters in the subject and on each line of the body of your email. Do not put spaces in between any parameters.

------------------
BASIC GRIB REQUEST
------------------

SUBJECT OF YOUR EMAIL:
grib

BODY OF YOUR EMAIL:
latitude,longitude

DESCRIPTION:
The subject of your email needs to be \"grib\" without the quotes. The body of your email should be one line with your latitude and longitude in decimal form (negative west/south, positive east/north) separated by a comma, no spaces. You will receive a GRIB1 file with winds and sea heights data for 24, 48, and 72 forecast hours, covering +5 lat/lon and -5 lat/lon from the lat/lon values you submit.

EXAMPLE:
20,-150

For this example, you will receive a GRIB1 file containing winds and sea heights data for the 24, 48, and 72 forecast hours covering 15N to 25N and 155W to 145W.

If you require more/different parameters and forecast hours, continue reading below for more advanced instructions on how to retrieve data from our automated system.

ADVANCED GRIB REQUEST
---------------------

SUBJECT OF YOUR EMAIL:
Determines which version of GRIB you will receive (grib1 or grib2)-
\"grib\" or \"grib1\" or \"grib2\"

\"grib\" or \"grib1\": You will receive a GRIB1 file. Compatible with most GRIB viewers.

\"grib2\": You will receive a GRIB2 file. Less compatible than GRIB1.

BODY OF YOUR EMAIL:

REQUIRED Line 1 - Location:
latitude,longitude,range

Latitude: Required. Specifies the center latitude of the GRIB data in decimal form, negative south, positive north.

Longitude: Required. Specifies the center longitude of the GRIB data in decimal form, negative west, positive east.

Range: Optional, default is 5. The range is both added and subtracted from your lat/lon values to determine the upper and lower boundaries of the GRIB data.

OPTIONAL Line 2 - Forecast Hours:
hour1,hour2,hour3-hour4,etc.

Forecast Hours are optional, default is 24,48,72. You can leave this line empty or specify a dash (-) with no values to use the default. If specified, you can choose individual hours separated by commas, and/or a range between two hours using a dash (-) and all forecast hours in that range will be included.
Hours available range from 3 to 180, with data every 3 hours from 3 to 60, and then every 6 hours from 60-180.

OPTIONAL Line 3 - GRIB Parameters:
param1,param2,param3,etc.

GRIB Parameters are optional, default is winds and seas. If specified, you can choose from the following paramaters (without quotes, and please note that many parameters have multiple aliases, you only need to specify one alias per parameter):

U and V component of winds (m/s): \"winds\" , \"wind\" , \"ugrd\" , \"vgrd\" , \"uvgrd\".
Significant Wave Height (m): \"seas\" , \"waves\" , \"heights\".
Wind Gust (kts): \"gust\".
Surface Pressure (mb): \"prmsl\" , \"mslp\" , \"pressure\".
Precipitation (in/hr): \"apcp\" , \"precip\".
Temperature (C): \"tmp\" , \"temp\" , \"temperature\".
Relative Humidity (%): \"rh\" , \"humidity\" , \"humid\".
Cloud Cover (%): \"tcdc\" , \"clouds\" , \"cloud\".
Primary Wave Directions: \"dirpw\" , \"wavedir\" , \"directions\" , \"direction\".
Primary Wave Periods: \"perpw\" , \"waveper\" , \"periods\" , \"period\"

EXAMPLES:

EXAMPLE 1-

-35,80,10
12,24,144-162

DESCRIPTION: Winds and sea heights data for the 12,24,144,150,156,162 forecast hours, covering 45S to 25S and 70E to 90E.

EXAMPLE 2-

25,-70,3
15,48-72,120
seas,directions,periods

DESCRIPTION: Sea heights, wave directions, and wave periods for the 15,48,51,54,57,60,66,72,120 forecast hours covering 22N to 28N and 73W to 67W.
