OCO-2 orbits the world every 16 days and collects data in its orbit path, which is what you show in your first attachment "OCO-2-1". If you are wanting to see "gap-filled" data, I'd like to direct you to the OCO2_GEOS_L3CO2_MONTH_10r and OCO2_GEOS_L3CO2_DAY_10r products which are assimilated products aggregated by monthly and daily averages, respectively. These products are compatible with our online web tool called Giovanni (https://disc.gsfc.nasa.gov/information/tools?keywords=Giovanni&title=Giovanni) which allows for easily customizable imagery, including selecting area by country as you mentioned. I think this dataset and Giovanni will be helpful. Please see my screenshots which show how I selected the data and North America, as well as the image output.

Hi

Does anyone download actual resolution CO2 data (2.25 km x 1.29 km). If anyone did, may you upload one file here?

Would OCO-2 Level 3 data be useful to you? See this Data Product Landing page:

Thank you for respond.

Have you download data with orginal resolution? (1.29-2.25 km). if yes how did and how visualise data?
May you upload one data here?

It is useful, but l could not download with original size (2.25-1.29km). If you download successfully may you upload one file here?
and how did you visualize?

Are you seeking data for specific locations? You should be able to download data at original resolution as Level 2 files, but it is not mapped to a grid, so you would only get the footprint data values.

Yes, the location is specific. what is resolution in level 2? How may l get this data? is it points data?

Here is more information on the OCO-2 level 2 data. The data image shows what the Level 2 daily data look like, which are discrete points along the ground track of the sensor.
