Sentences with phrase «forcing estimation method»

Accordingly, the forcing estimation method relies upon a model exhibiting a fairly linear climate response, and hence having a climate feedback parameter (and an effective climate sensitivity) that does not vary with time (in addition to having a temperature response that is proportional to forcing).

Not exact matches

The sensitivity, shown in Supplementary Table 6, of TCR estimation using the difference method to choice of base period when using a 2000 — 09 final period is explicable primarily by poor matching of volcanic forcing when base periods other than 1861 — 80 are used.

However, Supplementary Figure 4 shows that the chosen difference method provides stable estimation of model TCRs provided that the final decade has, like the 1861 — 80 base period, low volcanic forcing.

As discussed in some detail in LC15, sensitivity estimation using an energy budget difference method is sensitive to variations between the base and final periods in volcanic forcing, due to its very low apparent efficacy, so periods with matching volcanism should be used.

Moreover, as the iRF estimation method involves the climate state — including water vapour and clouds — being fixed in 1850, it does not appear that stratospheric water vapour forcing would be included in Historical iRF (nor in GHG iRF).
