Sentences with phrase «net decreasing toa»

Not exact matches

If it is in an isothermal layer, it will radiate upward as much as downward; it will decrease the baseline TRPP net flux and increase the baseline TOA flux by the same amount, but it will decrease the baseline TOA flux by a greater amount if it is absorbing radiation with a higher brightness temperature from below (the baseline upward flux at TRPP), so it will increase the amount by which the baseline net flux at TRPP is greater than that at TOA.

For a small amount of absorption, the emission upward and downward would be about the same, so if the upward (spectral) flux from below the layer were more than 2 * the (average) blackbody value for the layer temperature (s), the OLR at TOA would be reduced more than the net upward flux at the base of the layer, decreasing CO2 TOA forcing more than CO2 forcing at the base, thus increasing the cooling of the base.

«The overall slow decrease of upwelling SW flux from the mid-1980's until the end of the 1990's and subsequent increase from 2000 onwards appear to caused, primarily, by changes in global cloud cover (although there is a small increase of cloud optical thickness after 2000) and is confirmed by the ERBS measurements... The overall slight rise (relative heating) of global total net flux at TOA between the 1980's and 1990's is confirmed in the tropics by the ERBS measurements and exceeds the estimated climate forcing changes (greenhouse gases and aerosols) for this period.
