Sentences with phrase «change in albedo»

Changes in vegetation = > changes in albedo / CO2 levels.

Project Earthshine data show changes in albedo shown in blue, ISCCP - FD shown in black and CERES in red.

However, there are also changes in the albedo of snow due to growth of biological communities based on algae when nutrients are deposited on snow.

«Via satellite we received a continuous data feed on changes in albedo on the ice floe where we placed the SRB.

For one thing, the fit neglects lags in the system (such as those resulting from ocean heat uptake) and it also neglects changes in albedo and other radiative factors.

That's pretty alarming, especially when considered in the context of other positive feedbacks including changes in albedo from melting icecaps and release of carbon and methane from thawing permafrost.

Also, if you want to compare the percent change in albedo of 0.134 (too high, but assume it correct for the moment) with a 1 % reduction, the latter would be 1 % of about 100 W / m ^ 2, not 1 % of 340 W / m ^ 2, and would yield a value of about 1 W / m ^ 2.

«The significance of these shortcomings is not yet fully known, but model studies of hypothetical slab - ocean worlds suggest that interhemispheric changes in albedo can grossly affect the climate states of those worlds, shifting the ITCZ [Voigt et al., 2013, 2014; Frierson and Hwang, 2012] and altering the amount of heat moved poleward [e.g., Enterton and Marshall, 2010].»

I have often wondered how the GCMs handle changes in albedo from increased cloud cover.

25 Uncertainties Changes in atmospheric water vapor — Changes in cloudiness — Changes in albedo Carbon budgets Aerosol particles — Direct effects — Impact on clouds — Black carbon

Figure 2 shows changes in albedo calculated in Palle 2004 from reconstructed satellite data (black line) and Earthshine measurements (blue line).

Similarly, changes in terrestrial vegetation, such as the replacement of forests by tundra, feed back into the atmosphere via changes in both albedo and latent heat flux from evapotranspiration.

Consider the hemispherical distribution of land vs water to gain a sense of the size of the mismatch (and the subsequent relative changes in albedo between glaciation and interglacial).

Figure 12: «Earthshine changes in albedo shown in blue, ISCCP - FD shown in black and CERES in red.

I was interested not so much in the forcing effect of clouds themselves so much as the change in albedo which might result from a change in the overall extent of global cloud cover.

# 187 — «I was interested not so much in the forcing effect of clouds themselves so much as the change in albedo which might result from a change in the overall extent of global cloud cover.»

As PeterW in # 13 noted, and as I am sure you are aware, the change in albedo is bound to have all sorts of detrimental effects.

From the point of view of climate modelling the all - gone moment isn't as important as the magnitude of the change in albedo — particularly in the spring, summer and autumn.
