@yantosca @msulprizio I have also been having some recent issues using the latest develop branch of the standalone HEMCO MEGANv2.1 extension (https://github.com/geoschem/HEMCO/blob/dev/src/Extensions/hcox_megan_mod.F90) and seemingly the diagnostic outputs for monoterpenes, e.g.,...

@Yujie-W Thank you for these amazing datasets! Can you tell me if GriddingMachine also will have a global gridded forest cover fraction (FCF) dataset available soon (e.g., from MODIS)? Thank...

That would be great, thanks Yujie!! On Mon, Feb 6, 2023, 6:32 PM Yujie Wang ***@***.***> wrote: > @Yujie-W Thank you for these amazing > datasets! Can you tell me...

@Yujie-W Hi, just checking in to see if/when the MODIS FCF dataset will be available from GriddingMachine. Thank you!

@Yujie-W Also, a suggestion. For your forest canopy height (CH) datasets, you could add the [GEDI (Global Ecosystem Dynamics Investigation)](https://gedi.umd.edu/) LIDAR observations too. While GEDI itself is limited in expanse...

@JianpingHuang-NOAA @ytangnoaa The EBI solver issue can be caused by a many different issues with input variables to the solver. As Youhua mentioned, this EBI solver issue appears in both...

> @ytangnoaa @drnimbusrain Thanks for your suggestion and information. It takes about 3 hours for the AQM8.0 package with the latest dev branch of UFSWM and CMAQ5.4 to complete 72-hr...

> @drnimbusrain I am still using the EBI solver not Rosenbrock solver @JianpingHuang-NOAA We recommend switching to the ROS3 solver, as this seems more stable and faster from Wei's intial...

@JianpingHuang-NOAA Please see Youhua's response: " FYI, Wei Li tested the Rosenbrock solver (ROS3) (https://ir.cwi.nl/pub/10743/10743D.pdf), which shows much **more consistent timing without the converge issue, and can reduce the overall...

Great work Wei!! While I am still concerned with input met/land in UFS-AQM potentially causing these EBI solver issues, moving to the ROS3 solver seems like a good path forward!
