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.
5. Snow on Venus? Venus Express discovered a surprisingly cold region high in the planet's atmosphere, where conditions may be frigid enough for carbon dioxide to freeze out as ice or snow. Although the planet's surface is like a red hot furnace, conditions are very different at an altitude of 125 km, where Venus Express revealed a very frigid layer with a temperature of around -175Â°C. The unexpected cold layer is far chillier than any part of Earth's atmosphere, despite Venus being much closer to the Sun. The discovery was made by studying light from the Sun as it passed through the atmosphere, revealing the concentration of carbon dioxide gas molecules at various altitudes along the terminator â the dividing line between the day and night sides of the planet.
