CHAMP, Version 2.0 includes the following enhancements: Capability to model the 0.2% annual chance event (500-year) has been added to CHAMP. New inputs for the 500-year event include wave height, wave period and wave setup. Erosion for the 500-year event is based on a dune reservoir of 1030 square feet.See Procedure Memorandum 47 for additional guidance on coastal modeling of the 0.2% annual chance flood.Added a user option under the Transect menu to round all station numbers to the whole foot.HAMP, Version 2.0 includes the following enhancements: Capability to model the 0.2% annual chance event (500-year) has been added to CHAMP.

Composition of the atmosphere of Venus. The chart on the right is an expanded view of the trace elements that all together do not even make up a tenth of a percent. The atmosphere of Venus is composed of 96.5% carbon dioxide, 3.5% nitrogen, and traces of other gases, most notably sulfur dioxide.
Scientists think that Venus used to be more similar to Earth, with lower temperatures and even liquid water on the surface of the planet. At some point, billions of years ago, the planet started to heat up. At some point, all the water on the surface evaporated into the atmosphere. Water vapor is an even more powerful greenhouse gas than carbon dioxide and this caused temperatures to rise even more. Then the surface of Venus got so hot that the carbon trapped in rocks sublimated into the atmosphere and mixed with oxygen to form even more carbon dioxide.
