Hello,
There are different types of albedo data in our Giovanni system. Click on the link below to access Giovanni with these variables selected. Giovanni is not difficult to use; you can examine the User Guide to get started, and I will be glad to assist if you encounter difficulty.
https://giovanni.gsfc.nasa.gov/giovanni/#service=TmAvMp&starttime=&endtime=&variableFacets=dataFieldMeasurement%3AAlbedo%3BdataProductPlatformInstrument%3AMERRA-2%20Reanalysis%2CNLDAS%20Model%3B&dataKeyword=Albedo
I could not exclude the "ISCCP Cloud Albedo" with the search facets, but the other variables are surface albedos. Giovanni does not have shapefiles for cities, so you will have to use a bounding box for approximate city boundaries, which could be determined with lat/lon coordinates on Google Maps. The NLDAS variables are for land areas only, so if the bounding box includes water (for a coastal city like Chicago or Boston), the values should only be for albedo on land. The MERRA-2 Reanalysis variables may be different in this regard.
I hope this will be useful for your project.
