Sentinel-2 has resolutions of up to 10 meters (depends on the bands, please see link 1) and is operational at a high repeat cycle.

Sentinel-2 images date back to 2014 and can be searched and downloaded after free registration the follwing services:

• Sentinel data hub: https://scihub.copernicus.eu/dhus/#/home
• PEPS: https://peps.cnes.fr/rocket/#/search?maxRecords=50&view=list
• USGS Earth Explorer: https://earthexplorer.usgs.gov/

If you need data before 2014, you can search within the Landsat collection which dates back to the 1980s. They have resolutions of 30m and a huge image archive:

Dear Rosa,

You may also check in United Nations SPIDER (see link below).

Dear Rosa

The simplest way to browse Copernicus Sentinel-2 optical images is via synergise Sentinel Playground.

I suggest to follow the attached link to directly view Sentinel-2 images on the fly. This will indicate which images (on which date) are relevant, based on cloud conditions.

Thank you very much Andreas and Jose. I had already tried the copernicus but after signing in i cannot get the sat maps for the area I am interested in. I might not know enough what I should be looking for but i have tried different combination of data sets without results (No products found). With USGS i managed to get jpeg and tiff images from sentinel2 but not enough quality. Maybe there isn't much for the area I am looking for. My study period goes from April 2016 to June 2017. 

And the UN-Spider, I seem unable to find anything for the area of interest. 

Thanks again for your prompt response, If you think of something else i can try, let me know.

Best regards

Rosa

In addition, in case that you want a higher resolution data for specific project, you can also make use of the Third Party Mission data delivered by ESA (normally via project submission). Please check https://earth.esa.int/web/guest/pi-community/apply-for-data/3rd-party 

Regarding Andreas' comment, Sentinel-2A was launch on June 2015, not in 2014, just to avoid confusions. Was Sentinel-1A to be launched in April 2014. Hence, if you need data before August 2015 you should look into some other satellite products. 

Unfortunately I am unable to help, but thank you for reaching out, and good luck.
