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.


 

hi paul
I will send you the file with complete geographical details. If possible, please correct my data. I really don't know what to do anymore. Please, please do this. Thank you for your cooperation.
Port Latitude Longitude
Anzali Port 37.473°N 49.459°E
Chabahar Port 25.291°N 60.643°E
Shahid Rajai Port 27.138°N 56.184°E
Below, in addition to my own files, I am also sharing a wave data file that I got from a meteorological site, which is related to Iran. I extracted the wave data from this file. This file is related to the years 2015 to 2025.
 

Hi Mohsen,

Attached is a version of the "Bandar_Shahid_Rajaee_TimeSeries_SAM_Final.csv" file that should work.

This file contains data for one year (2015). SAM does not support weather files with more than one year of data.

I changed the time zone format from +3:30 to 3.5 so that SAM correctly reads the time zone.

I changed the "Wave Energy Period" heading to "Energy Period".

Best regards,
Paul.
