Weather satellite[edit]

Weather satellites and seismometers - any practical help for tsunamis as like for hurricanes and typhoons?

Question 1:- Can weather satellites detect long and high wave heights such as caused by Tsunamis as in earthquake in Indian Ocean off North Sumatra on 26-12-2004 if alerted by seismometers immediately when large ocean quakes occur or large meteors splashes.?

Question 2:- Does any Geology body alert Oceanography, Maritime or Naval bodies to monitor Tsunamis occurrences, track and record their path for rescue purposes, predict and post warnings of tsunami arrival times at various islands and coastlines?

Question 3:- Are the existing satellites able to record the land covered by tsunamis and coastal changes for rescue purposes and also for preparation for next tsunami?

Question 4:- Surface wind, storm conditions and tides - could they be factored into effect on tsunami severity?. Tides can have effect on people on beaches and fishermen presence on or off shore.

Can somebody please give some answers or set up some warning system.

Thomas Ng

I can understand your concern given recent developments.

1: In satellite observation, you lose most of the vertical resolution of the Earth. It's virtually impossible to tell the height of the features below a satellite without a RADAR or LIDAR system. Such systems do exist on certain polar-orbiting satellites but coverage is spotty. It might be possible to set up a system that could watch for large-scale deformations, but not with currently existing equipment.

2: USGS and other bodies do have a limited tsunami warning program [1], but it is of limited effectiveness and is not effective for immediate threats.

3: Given the transient nature of tsunamis, it's hit-or-miss whether an imaging satellite will be overhead at the time, at least one that would be open to public scrutiny rather than a satellite belonging to intelligence operations, and such images would be of marginal help unless they could be delivered instantly to local emergency agencies.

4: Storm conditions are usually minor compared to the power of major tsunamis. It's true that they might have an impact on the behaviour of people before the tsunami strikes, but it would probably be of negligible influence to the total damage.

There are many areas of technology that would need to be improved before some of these ideas could be implemented. I would suggest sending some of them along to space and seismology agencies so they may have a look at them to determine their implementability with current and future observation systems.

Last Paragraph[edit]

The last paragraph (mentioning the oil well fires in Kuwait) seems totally out of place, especially with no references or links to appropriate images. ahpook (talk) 18:20, 26 August 2008 (UTC)[reply]

Inline references?[edit]

Although the article appears to be within reason factually, it's impossible to tell without inline references. Once they're added, this article could be upgraded to C or B class in no time. Thegreatdr (talk) 06:42, 3 January 2009 (UTC)[reply]

First?[edit]

1959 Flat plate radiometer designed by V.E. Suomi and R.J. Parent for the first Earth Radiation Budget Experiment (ERBE) flew on Explorer-7. The flat plate radiometer (FPR) system was designed to provide a measurement of the global distribution of reflected solar and longwave radiation leaving the earth. With this experiment, Suomi established the important role played by clouds in absorbing radiated solar energy, setting the stage for integration of satellites into the field of meteorology (A Man for All Seasons) —Preceding unsigned comment added by 71.150.248.237 (talk) 05:09, 24 March 2010 (UTC)[reply]

See Explorer 7; it's now mentioned in first images of Earth from space. fgnievinski (talk) 17:19, 5 October 2020 (UTC)[reply]

Why a paragraph about environmental satellites in the lede?[edit]

Paragraph 3 of the lede:
"Other environmental satellites can detect changes in the Earth's vegetation, sea state, ocean color, and ice fields. For example, the 2002 Prestige oil spill off the northwest coast of Spain was watched carefully by the European ENVISAT, which, though not a weather satellite, flies an instrument (ASAR) which can see changes in the sea surface."
Okay. So, we acknowledge that there are satellites that are not weather satellites, though tangentially related to weather satellites. We even acknowledge that ENVISAT is not a weather satellite, while describing instruments that can be used for climate analysis - but not weather. Why? The lede is supposed to be a summary of the article. Yet we use roughly one-fourth of the lede to describe...not weather satellites.

Makes no sense. I would propose removing the entire paragraph, as it has nothing to do with this article. Anastrophe (talk) 07:03, 10 September 2019 (UTC)[reply]
