«Global mean time series of surface - and satellite - observed low - level and total cloud cover exhibit very large discrepancies, however, implying that artifacts exist in one or both data sets... The surface - observed low - level cloud cover time series
averaged over the global ocean appears suspicious because it reports a very large 5 % - sky - cover increase between 1952 and 1997.
They are calculated as daily turbulent air - sea
fluxes over global oceans with a spatial resolution of 0.25 ° in longitude and latitude.
Here the adjustment is determined by (1) calculating the collocated ship - buoy SST difference
over the global ocean from 1982 - 2012, (2) calculating the global areal weighted average of ship - buoy SST difference, (3) applying a 12 - month running filter to the global averaged ship - buoy SST difference, and (4) evaluating the mean difference and its STD of ship - buoy SSTs based on the data from 1990 to 2012 (the data are noisy before 1990 due to sparse buoy observations).
New gridded daily wind fields from Metop / ASCAT scatterometer retrievals are produced in near real - time
over global ocean with a spatial resolution of 0.25 °.

This is the first observation - based investigation of the relationship between ocean bottom pressure and sea
level over the global ocean on interannual time scales.
Total column water vapour has increased
over the global oceans by 1.2 ± 0.3 % per decade from 1988 to 2004, consistent in pattern and amount with changes in SST and a fairly constant relative humidity.
It is important to mention that these processes are not
uniform over the global ocean and thus the disequilibrium is not only between ocean and atmosphere, but there are also differences in radiocarbon levels within the ocean.
Gridded daily wind vector and wind stress fields,
estimated over global ocean from QuikSCAT scatterometer (referred as DQSCAT) data, have been updated.
The main improvements with respect to V2 version flux products (Bentamy et al, 2008) are related to the improvements of the specific air humidity estimation from radiometer measurements, to the assessment of the surface winds retrieved from QuikSCAT scatterometers, and to the use of the new objective method allowing the calculation of flux
analyses over the global oceans.

The paper by Tamisiea et al. (2010) examines how the exchange of water between the atmosphere, oceans, and continents can contribute to the water cycle, load the Earth and change its geoid, and cause the annual variations in relative sea
level over the global ocean.

(a) Linear trends in precipitable water (total column water vapour) over the period 1988 to 2004 (% per decade) and (b) the monthly time series of anomalies, relative to the period shown,
over the global ocean with linear trend.
The two leading CSEOF modes were subsequently projected onto the altimeter data from 1993 to present and averaged
over the global ocean to arrive at what we refer to as a GMSL ENSO correction.
