format data

Hello
Good morning
I have three wave data files related to three Iranian ports. No matter what I do, the SAM software cannot read this data. If it is possible, please check this data and email it to me after it is corrected
Thank yo

Hi Moshen,

Here is a link to the SAM CSV format for Marine Energy file format descriptions in Help: samrepo.nrelcloud.org/help/weather_format_csv_marine_energy.html

Be sure to look at the description for time series data (not frequency of occurrence data).

Attached is the default time series wave resource data file that you can use as a model for your files. (You can also find this file in the "wave_resource_ts" folder in your SAM installation folder.)

I noticed a few things in your files:

Rows 1 and 2 are missing. These rows contain information like latitutde, longitude, and time zone.

The time stamp columns (Day, Hour, Minute) appear to be inconsistent. If this data contains 3-hour data, I would expect the first three rows to have time times like this:

Day, Hour, Minute
1,0,0
1,3,0
1,6,0
1,9,0
1,12,0
1,15,0
1,18,0
1,21,0
2,0,0
2,3,0
etc.

Instead, the time stamps in your file look like this:

Day,Hour,Minute
1,18,0
2,9,0
3,12,0
4,18,0
5,6,0
6,21,0
etc.

For 3-hour data, the file should contain 2920 rows of data:

24 h/day / 3 h/timestep = 8 timesteps/day
8 timesteps/day * 365 days/year = 2920 timesteps

Best regards,
Paul.
