Description
October-November 2011 time series (3-day running-mean filtered, daily-average values) of net radiative heating rate (K/day) from thermodynamic budgets (black) and the CERES product (red) for the northern (upper panel) and southern (lower panel) sounding arrays, and from the PNNL CombRet product for Gan Island (green). Solid (dashed) black curves are the net-tropospheric radiative heating rates with (without) inclusion of terms involving the effects of rain. Numbers in parentheses are two-month mean values. Light (dark) shading denotes periods of R/V Revelle (R/V Mirai) port calls. From Johnson et al. (2015, J. Atmos. Sci., in press).
AMF measurements from Addu Atoll (Gan Island) during AMIE/DYNAMO/CINDY have been used to retrieve radiative heating rates during the experiment (Feng et al. 2014, J. Atmos. Oceanic Technol.). Independent estimates of tropospheric column-integrated radiative heating rates have been recently obtained from sounding-based heat and moisture budgets and compared to those from the AMF-based retrievals as well as those from CERES (Johnson et al. 2015, J. Atmos. Sci.). The October-November 2011 mean, net-tropospheric radiative heating rates from the budgets and CERES for the northern sounding array agree well (~ -0.6 K/day), whereas the estimate from Gan Island based on the PNNL CombRet retrievals shows slightly more cooling (~ -0.8 K/day), likely due to the undersampling of cirrus by the instruments on the island. Details of the interecomparisons will be presented.
