-====== Warm rain diagnostics (COSP and non-COSP) ======
-=====Objective=====
-Warm rain statistics may provide a process-based observational constraint on parameterized precipitation in GCMs, specifically on the cloud lifetime effect (see Johannes's [[https://home.uni-leipzig.de/jmuelmen/files.html?name=aerocom-171009.pdf|Helsinki AeroCom meeting slides]]).
-We have received base-state warm rain diagnostics from [[aerocom:warm-rain-diagnostics#Models participating so far|a number of models]], but it would be especially useful to see how the warm diagnostics respond to changes in the warm rain (autoconversion/accretion) parameterization.  We would therefore like to piggyback on existing AeroCom experiments (e.g., the
-multi-model PPE) with as little extra work as possible required.
-=====Required model diagnostics=====
-If you are interested in participating and are **COSP-enabled**, please see [[aerocom:warm-rain-diagnostics#COSP diagnostics|COSP diagnostics]].  If you **cannot run COSP**, we would still be delighted to receive [[aerocom:warm-rain-diagnostics#Non-COSP diagnostics|simpler, non-COSP, diagnostics]].
-====COSP diagnostics====
-====Non-COSP diagnostics====
-To participate, please save one of the following sets of diagnostics:
-  - 3D snow and rain mixing ratios
-  - 3D snow and rain fluxes
-  - 2D snow and rain water paths
-The required time frequency is 6-hourly non-accumulated.  If this is not feasible for the requested 3D fields, it is possible to implement the warm-rain fraction as an online diagnostic (with monthly-mean 2D output) in the model; please [[aerocom:warm-rain-diagnostics#Contact|contact Johannes]] for details.
