Sentences with phrase «errors in ocean heat content»

Even extending to pre-Argo periods, with a long period the errors in ocean heat content values have to be very large to have a major effect on the mean rate of heat uptake over the period.

Not exact matches

There is still some discrepancy remaining, which could be due to errors in the satellite measurements, the ocean heat content measurements, or both.

And since we don't have good ocean heat content data, nor any satellite observations, or any measurements of stratospheric temperatures to help distinguish potential errors in the forcing from internal variability, it is inevitable that there will be more uncertainty in the attribution for that period than for more recently.

So given a forcing (in this case 0.85 W / m2 (= 1.6 W / m2 minus 0.75 W / m2 for the ocean heat content change), and a temperature change 0.7 °C, the sensitivity is 0.7 / 0.85 = ~ 0.8 °C / (W / m2)(leaving off the error bars for clarity)- gavin]

It is certainly true that a very small temperature bias that is not random from instrument to instrument, but instead is the same over a large number of profiles can create systematic error in global estimates of ocean heat content.

The error bars on the CERES retrievals, particularly when all 4 sensors are available are significantly less than the (reported) error bars on the ocean heat content data in the Lyman et al work.

However, it's easy to assess the error in the global mean ocean heat content based on the measurement error and spatial variability, and that is done in the Willis et al paper.

The error is small enough to have confidence that the ocean heat content has been increasing in the past 15 years, during the so called «hiatus» in global warming.

Moreover, the scientists called for continued support of current and future technologies for ocean monitoring to minimize observation errors in sea surface temperature and ocean heat content.

Domingues et al (2008) and Levitus et al (2009) have recently estimated the multi-decadal upper ocean heat content using best - known corrections to systematic errors in the fall rate of expendable bathythermographs (Wijffels et al, 2008).

Assuming for the sake of argument that «the pause» is not an instrument error and the troposphere hasn't gotten any warmer in 16 years then this raises the question of how ocean heat content could be rising which, according to ARGO, at least the upper half of the ocean is accumulating thermal energy.

«Our results demonstrate how synergistic use of satellite TOA radiation observations and recently improved ocean heat content measurements, with appropriate error estimates, provide critical data for quantifying short - term and longer - term changes in the Earth's net TOA radiation imbalance.

What are the error bars in calculating the heat content of an entire ocean from the sparse, unreliable (pre-ARGO) temperature data available?

Figure 3.2: b) Observation - based estimates of annual five - year running mean global mean mid-depth (700 — 2000 m) ocean heat content in ZJ (Levitus et al., 2012) and the deep (2000 — 6000 m) global ocean heat content trend from 1992 — 2005 (Purkey and Johnson, 2010), both with one standard error uncertainties shaded (see legend).

Looking at the last decade, it is clear that the observed rate of change of upper ocean heat content is a little slower than previously (and below linear extrapolations of the pre-2003 model output), and it remains unclear to what extent that is related to a reduction in net radiative forcing growth (due to the solar cycle, or perhaps larger than expected aerosol forcing growth), or internal variability, model errors, or data processing — arguments have been made for all four, singly and together.
