Summary

...


We run a 1 degree FC compset, FC5AV1C-L, simulation for 6 years and create 5-year (year 2 to 6) climatologies from it. We plot climatologies vs observations and vs default configuration. The default configuration consists of default hydrostatic dycore with default settings. Preliminary runs are described in /wiki/spaces/COM/pages/780664997 (with preqx dycore) and in /wiki/spaces/COM/pages/941096965 (with theta dycore), each relevant run also has entry for its climatologies.

(replace text below when the final run is ready)

With theta dycore, we only explore hydrostatic option for now. In Theta-l and SL coupled, 1 degree, anvil , Run1 contains parameters for theta+SL, but uses default settings for topography divergence damping. Run 20 is more optimal than Run 1 wrt divergence damping and number of HV sub cycles. We will produce 1 more simulation, with the same divergence and HV parameters as in Run 20, but with more optimal TOM dissipation. This last run is expected to be if not the final configuration than very close to it. We will have model vs model climatologies for it.

As a shortcut, here are climatologies for Run 20 (the closest to the final configuration so far) vs observations: https://web.lcrc.anl.gov/public/e3sm/diagnostic_output/onguba/theta/theta-sl-run2.12775/viewer/latitude-longitude/index.html

Compare these with the default run (also plotted agains observations): https://portal.nersc.gov/project/acme/onguba/variability/preqx-default-march30.190330and190331-0002-0006/viewer/latitude-longitude/index.html 

We are adding tests for theta dycore and SL into testing harness of E3SM.

...

transport was first evaluated in the preqx dycore using the E3SM v1 atmosphere at 1 degree. Results and some technical details are presented in /wiki/spaces/COM/pages/916324466 . The SL transport was shown to be 6x faster.

With theta dycore, we only explore hydrostatic option for now. Preliminary configuration for theta-l dycore and SL transport is given as in Run6 /wiki/spaces/COM/pages/997752860 .

Validation Test 1

Validation Test 1: preqx dycore and SL transport for 1 degree

...


We ran FC5AV1C-L for 6 years with preqx dycore and SL transport and made 5-year climatologies. With diagnostics package, we compared climatologies of the new run to the default (preqx dycore, Eulerian transport, default E3SM settings) run from the same compset. Results are in https://portal.nersc.gov/project/acme/onguba/sl/sl-fastest.2369911-latlon-vs-f2/viewer/latitude-longitude/index.html for latlon plots and in https://portal.nersc.gov/project/acme/onguba/sl/sl-fastest.2369911-zonal-vs-f2/viewer/pressure-latitude/index.html for zonal plots. Our understanding from communicating with C. Golaz is that differences are relatively minor and are expected.

This task required new coupling mechanisms between homme and physics (ftypes). Tests for all coupling schemes are now in nightlies with baselines.

How was XXX be tested? i.e. how do we know when we have met requirement XXX. Will these unit tests be included in the ongoing going forward?

...

There are some differences, in particular, for seasonal jets and for tropopause T200. An expert should evaluate them.

Test for theta-l dycore and SL transport was added to nightlies with baselines.
