Low clouds are found from near the surface up to {{convert|6500|ft|abbr=on|order=flip|-2}}.<ref name="Definitions" /> Genus types in this level either have no prefix or carry one that refers to a characteristic other than altitude. Clouds that form in the low level of the troposphere are generally of larger structure than those that form in the middle and high levels, so they can usually be identified by their forms and genus types using satellite photography alone.<ref name="Cloud type identification" />
* Genus [[stratocumulus]] (Sc) – This genus type is a stratocumuliform cloud layer of limited convection, usually in the form of irregular patches or more extensive sheets similar to altocumulus but having larger elements with deeper-gray shading.<ref name="stratocumulus">{{Cite web |year=2017 |editor-last=World Meteorological Organization |title=Stratocumulus, International Cloud Atlas |url=https://cloudatlas.wmo.int/clouds-genera-stratocumulus.html |url-status=dead |archive-url=https://web.archive.org/web/20170510035919/https://cloudatlas.wmo.int/clouds-genera-stratocumulus.html |archive-date=10 May 2017 |access-date=16 May 2017}}</ref> Stratocumulus is often present during wet weather originating from other rain clouds, but can only produce very light precipitation on its own.<ref name="stratocumulus-precipitation">{{Cite web |year=2016 |editor-last=Met Office |title=Stratocumulus |url=https://www.metoffice.gov.uk/learning/clouds/low-level-clouds/stratocumulus |access-date=10 April 2018}}</ref>
* Species [[cumulus humilis]] – These are small detached fair-weather cumuliform clouds that have nearly horizontal bases and flattened tops, and do not produce rain showers.<ref name="cumulus">{{Cite web |year=2017 |editor-last=World Meteorological Organization |title=Cumulus, International Cloud Atlas |url=https://cloudatlas.wmo.int/clouds-genera-cumulus.html |access-date=16 May 2017}}</ref>
* Genus [[Stratus cloud|stratus]] (St) – This is a flat or sometimes ragged nonconvective stratiform type that sometimes resembles elevated fog.<ref name="stratus">{{Cite web |year=2017 |editor-last=World Meteorological Organization |title=Stratus, International Cloud Atlas |url=https://cloudatlas.wmo.int/clouds-genera-stratus.html |access-date=16 May 2017}}</ref> Only very weak precipitation can fall from this cloud, usually drizzle or snow grains.<ref name="drizzle">{{Cite web |year=2017 |editor-last=World Meteorological Organization |title=Drizzle, International Cloud Atlas |url=https://cloudatlas.wmo.int/drizzle.html |access-date=9 April 2018}}</ref><ref name="snow-grains">{{Cite web |year=2017 |editor-last=World Meteorological Organization |title=Snow Grains, International Cloud Atlas |url=https://cloudatlas.wmo.int/snow-grains.html |access-date=9 April 2018}}</ref> When a very low stratus cloud subsides to surface level, it loses its Latin terminology and is given the common name fog if the prevailing surface visibility is less than {{Cvt|1|km}}.<ref name="stratus-fog">{{Cite web |year=2000 |editor-last=Colorado State University |title=Stratus and Fog |url=http://rammb.cira.colostate.edu/wmovl/vrl/tutorials/satmanu-eumetsat/SatManu/CMs/FgStr/backgr.htm |access-date=9 April 2018}}</ref> If the visibility is 1&nbsp;km or higher, the visible condensation is termed [[mist]].<ref name="mist-fog">{{Cite web |year=2017 |editor-last=Met Office |title=Difference Between Mist and Fog |url=https://www.metoffice.gov.uk/learning/fog/difference-mist-and-fog |access-date=9 April 2018}}</ref>
