Jonathan McDowels's General Catalog of Artificial Space Objects includes that information. See the object catalog at (download links in the menu on the left). Specifically the length (longest dimension excluding antennas/solar arrays) and span (including everything) columns.


This question was partly addressed in a 1994 report (warning: not peer reviewed) by the Environmental Management of the Space & Missile Systems Command in the United States. Their focus was to consider the impact of deorbiting space debris on ozone at the time, and their conclusion was that deorbiting space debris has very little impact on stratospheric ...


The mass of Earth's atmosphere is 5E+18 kg and the Troposphere alone has 3/4's of that. With an average height of 13 km that makes its volume $4 \pi r^2 h$ or about 6.6E+18 m^3. If we break up one thousand 100 kg satellites into semi-porous PM2.5 particles that works out to be 1.5E-08 micrograms per cubic meter, and we generally worry about tens of ...


JSpOC - now 18th SPCS - uses following values: Payloads and platforms (5meters), rocketbodies and unknownobjects (3meters), debris(1meter) The catagorisation of each object can be found in the NORAD-SAT-CAT, you can access via Space Track Another database is the ESA-Discos-DB, which bases on real dimensions and not a catagorisation. But you need to apply ...
