Hiding The Decline : Envisat Sea Level

Falling Since 2008

Launched in 2002, Envisat is the largest Earth Observation spacecraft ever built. It carriesten sophisticated optical and radar instruments to provide continuous observation and

monitoring of the Earths land, atmosphere, oceans and ice caps. Envisat data collectively

provide a wealth of information on the workings of the Earth system, including insights into

factors contributing to climate change.

Its largest single instrument is the Advanced Synthetic Aperture Radar (ASAR), operating at

C-band, ensures continuity of data after ERS-2. It features enhanced capability in terms of

coverage, range of incidence angles, polarisation, and modes of operation. The improvements

allow radar beam elevation steerage and the selection of different swaths, 100 or 400 km

wide.

The Medium Resolution Imaging Spectrometer (MERIS) is a imaging spectrometer that

measures the solar radiation reflected by the Earth, at a ground spatial resolution of 300 m,

with 15 spectral bands in visible and near infra-red and programmable in width and position.

MERIS allows global coverage of the Earth every 3 days.

The primary mission of MERIS is the measurement of sea colour in oceans and coastal areas.

Knowledge of sea colour can be converted into a measurement of chlorophyll pigment

concentration, suspended sediment concentration and aerosol loads over marine areas. It is

also used for land and atmospheric monitoring.

Envisat (Environmental Satellite) is the follow-on to ERS-1 and ERS-2. Devoted to

environmental studies, and climate change in particular, its mission is to observe Earth's

atmosphere and surface. Built by Esa, the European Space Agency, Envisat is carrying ten

complementary instruments for observing parameters ranging from the marine geoid to high-

resolution gaseous emissions. Among these instruments are a radar altimeter, and the DORIS

orbitography and precise location system.

From 2002 to October 2010, Envisat's orbital period is 35 days, like ERS-2 and some of the

ERS-1 phases. As it is integrated in new international climate study programmes such as

Goos and Godae. Envisat thus forms part of the coming operational era in oceanography,offering near-real-time data access.

The RA-2 S-band module is definitively lost since 2008/01/18.

To ensure an additional 3 years lifespan, the Envisat satellite moved to a new lower orbit on

October 22, 2010. From 02 November 2010, for the Envisat extension orbit, the ground track

changes and consequently the repeat cycle changes: 30 days with 431 orbits per cycle instead

of 35 days-501 orbits per cycle.

Oops! It turns out sea level is hardly rising. Now, lets remove all of the adjustments to

Envisat data.


We see a rise rate which is about one-fourth of what the global warming community claims.

Even with all the adjustments, rates are about one-third of what the global warming

community claims.

1.2 mm/year is much lower than alarmist claims, but is about triple the mean of NOAA tide

gauges.

http://tidesandcurrents.noaa.gov/sltrends/MSL_global_trendtable.html

So, we can see that sea level claims are exaggerated by somewhere between 3-9X, which

seems to be in line with other bloated IPCC numbers.

The Topex/Poseidon satellite was launched on 10 August 1992 with the objective of

"observing and understanding the ocean circulation". A joint project between Nasa, the US

space agency, and Cnes, the French space agency, it carries two radar altimeters and precise

orbit determination systems, including theDorissystem.

Topex/Poseidon is laying the foundation for long-term ocean monitoring from space. Every

ten days, it supplies the world's ocean topography, or sea surface height, with unprecedentedaccuracy.

From the launching of Jason-1, in December 2001, the 2 satellites had one-day shift. On

September 15, 2002 Topex/Poseidon assumed a new orbit midway between its original

ground tracks. The former Topex/Poseidon ground tracks are now overflown by Jason-1. This

tandem mission demonstrates the scientific capabilities of a constellation of optimized

altimetric satellites. The mission ended on October 2005 due to a failure in a pitch reaction

wheel.

The Topex/Poseidon mission : an unrivalled success

Everybody, and in particular anyone who has been involved from the very beginning, is now

left with the feeling that they were part of a great adventure, from a technical and above all a

human perspective. During its thirteen years of operation, Topex/Poseidon witnessed many

developments and innovations and even some media success. As for its overall success, themission will be remembered both for the expected applications and the additional ones which

led to greater interest in this type of satellite data.

Geosat was the first mission to provide long-term high-quality altimetry data.

Geosat (GEOdetic SATellite) was launched in March 1985, and ended its mission in January

1990. Its primary task was to measure the marine geoid for the US Navy, but it also provided

measurements of sea state and winds which proved to be useful for operational Navy

purposes. Once this 18-month mission was over, the satellite was put on a 17-day repeat orbit(Exact Repeat Mission: ERM) which began on 8 November 1986, retracing Seasat's ground

tracks, and providing the scientific community, through Noaa, with altimeter data for over

three years.

The ERS satellites's (European Remote Sensing) main mission is to observe Earth, in

particular its atmosphere and ocean. Build by Esa, they carry several instruments, including a

radar altimeter. ERS-1 was launched in July 1991, switched off in June 1996 and retired in

March 2000.

ERS-1 flew on three different orbits:

a 3-day period for calibration and sea ice observation (from 12/28/1991 to 03/30/1992and from 12/24/1993 to 04/10/1994),

a 168-day period for geodetic applications (from 04/10/1994 to 09/28/1994 and from09/28/1994 to 03/21/1995).

a 35-day period for multi-disciplinary ocean observations (for the others dates),ERS-2, the follow-on from ERS-1, was launched in April 1995. It was used in tandem with

ERS-1 from August 1995 to June 1996, their identical orbits (35 days) having a one-day shift.

GFO,GeosatFollow-On was launched in February 1998. Its mission is to provide real-time

ocean topography data to the US Navy. Scientific and commercial users have access to these

data through Noaa. Its primary payload is a radar altimeter.

GFO follows the 17-day repetitive orbit of Geosat. After an onboard problem of overheating

reaction wheels in September 2008, GFO's transmitter was turned off for the final time the

November 26, 2008.

ERS-2 was launched in April 1995 as the follow-on fromERS-1, with which it was used in

tandem from August 1995 to June 1996, their identical orbits (35 days) having a one-day

shift.In June 2003, ERS-2's onboard tape recorder used for the altimeter data has experienced a

number of failures. This means that altimeter data are unavailable except for when the

satellite is within visibility of Esa's ground stations over Europe, North Atlantic, the Arctic

and western North America.

In July 2011, ERS-2 is put out of service by bringing down to a lower orbit. These deorbiting

procedures are done while the fuel is still sufficient to make the careful manoeuvres.

Launched in March 2002, theEnvisatsatellite is the follow-on toERS-1and ERS-2.
