ERA5-Land wind data

Hi all,

I am new to ERA5-Land usage. I wanted to get wind data for the island Curaçao (on January 2000) and used these coordinates North: 12.5°N South: 12.0°N East: -68.7°E West: -69.2°E to get the data. I read the file using Matlab, and got the results shown in the picture. Does anyone know why the values of the wind speed are not shown?

Many thanks,

Jasmine
