Technical note: Recommendations for diagnosing cloud feedbacks and rapid cloud adjustments using cloud radiative kernels
Published 2025-02-01“…<p>The cloud radiative kernel method is a popular approach to quantify cloud feedbacks and rapid cloud adjustments to increased <span class="inline-formula">CO<sub>2</sub></span> concentrations and to partition contributions from changes in cloud amount, altitude, and optical depth. However, because this method relies on cloud property histograms derived from passive satellite sensors or produced by passive satellite simulators in models, changes in obscuration of lower-level clouds by upper-level clouds can cause apparent low-cloud feedbacks and adjustments, even in the absence of changes in lower-level cloud properties. …”
