Condensed parts of Earth's atmosphere

Click For Summary

Discussion Overview

The discussion centers on the composition of condensed phases in Earth's atmosphere, specifically focusing on the amounts and types of condensed water (both liquid and solid) and other particulates such as dust. Participants explore the breakdown of these components and their implications for atmospheric science.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant inquires about the total amount of condensed water in the atmosphere, distinguishing between liquid and solid forms.
  • Another participant clarifies that the inquiry pertains to water suspended in the atmosphere as clouds, precipitation, and ocean spray.
  • A further response emphasizes the need to consider the total amount of dust in the atmosphere alongside condensed water, noting that not all dust is rock-based.
  • Participants mention various sources of atmospheric particulates, including organic and industrial origins, and provide examples such as sea salt, soot, and volcanic sources.
  • One participant discusses the dynamics of water in the atmosphere, explaining how clouds form from cooler air and how rain regulates water content, while also transporting dust and ions.

Areas of Agreement / Disagreement

Participants generally agree on the importance of distinguishing between different types of condensed phases in the atmosphere, but there is no consensus on the specific amounts or breakdowns of these components. Multiple views on the sources and types of particulates remain present.

Contextual Notes

Limitations include the lack of specific data on the amounts of condensed water and dust, as well as the complexity of categorizing different types of particulates in the atmosphere.

How much of Earth atmosphere consists of condensed phases?
What is the breakdown of these condensed phases between those that condense in atmosphere (water) and those that do not (rock)?

The total amount of water in Earth atmosphere is quoted as a 25 mm layer on average - total of about 13 000 km3. But this is total water, including vapour. What is the total amount of condensed water in atmosphere? How much of it is liquid, how much solid?

So you want to know much water is suspended in the atmosphere as clouds, precipitation, ocean spray, etc.?

Yes. The breakdown of stuff suspended in atmosphere - the condensed water in clouds (liquid and solid, as distinct from water vapour in the air between the cloud droplets or snowflakes) and rock - that is, total amount of dust in the whole atmosphere in the same time.

Not all dust will be rock.
Some will be of organic or industrial origin.
 
Some particulates from a NOAA blurb:
Water ice, PAN particles from auto exhaust, sea salt, rockdust, soot, VOG (Volcano sources), Carbon Dioxide ice, plant and fungal spores, Sulfur oxides. Dust plumes from bean and wheat processing, and copper & coal mining. The dust movement from the Sahara desert to Central and South America effectively moves soil nutrients across the Atlantic ocean, for example.

This is a partial list. It will take some work searching for data on one of these topics, let alone all of them.

What are you working on? NOAA has down loadable data sets so you can sort out this mess into what you need. Probably.

The atmosphere near clouds usually contain the same mass of water as the air with clouds. It is just that the clouds are parcels of slightly cooler or lower pressure atmosphere, so the water condenses and becomes visible. When the air contains too much condensate to be suspended it rains, which regulates the water content. That rain may carry the water down to where it is warmer, so the water may dissolve again, but into a different parcel of air. Dust particles and ions in the atmosphere are transported with the water while it is in the form of a condensate or rain.
