Do you use #ncview to quickly browse your #NetCDF files?

You are not the only one !

Of course, a problem with #ncview is that it comes with bad #colormaps, including many 🌈 rainbows 😭 .

But we have a solution for you !

Install #ncmaps and bring scientific colormaps to #ncview !

So here comes a little challenge:

Step 1) install #ncmaps (https://github.com/TomLav/ncmaps). Really easy.

Step 2) make a #ncview screenshot of a #NetCDF file using one of the ncmaps colormaps.

Step 3) Post it here below, explaining what the image shows, and naming the colormap used.

I'll #boost your contribution 😊!

@lavergnetho I first take this opportunity to thank you a lot for the colormaps! I use them for a long time and it's a life changer.

Attached is a screenshot of a climatology of the Stratification Control Index (simplified explanation: red = stratified by temperature, blue = stratified by salt)
We have 2 papers that use the SCI (plus other in prep), don't hesitate to read them!

@lavergnetho works well here. Just plotted the mean OSI SAF SST for July 2022 over France. Used the thermal colormap from cmocean.
Thanks a lot it definitely improves ncview visualisation!

@TGuinaldo Cheers Thibault for this nice example!

Keep them coming, folks. #ncmaps #ncview

@lavergnetho #ncmaps is definitely the best update to #ncview since 2017! I use it for quite some time now and don’t want to miss it anymore. Giant thanks for taking the pain out of ncview and even more for making this eye-candy solution publicly accessible!

Screenshots below show present-day #Antarctic bed topography and ice thickness from the #Bedmap2 dataset using colormaps topo and dense from #cmocean.

@juliusgarbe Thanks for the kind words, Julius! And a very nice use of #ncmaps indeed.

We also have to thank the original developers of #ncview: they thought ppl would want to add more colormaps and made it possible without compiling the code.

@lavergnetho Allright then, here's a view of the thermosteric sea level from the Levitus dataset. Thanks for the colormaps, I'll give you a star on github

@lavergnetho Here's mine Thomas 😀 It's sea surface temperature in the southwestern Mediterranean Sea, showing, what else 😅 , a wonderful Alboran gyre and a filament east of it, with missing data reconstructed with #DINEOF. I have tried the Roma colormap this time.

Thank you so much for this!!

@aida Cheers Aida !

Do as Aida, install #ncmaps (see ⬆️ of thread) and post a view of one of your #netCDF files !

@lavergnetho Oy, I can't even open the original ncview page at UCSD in my browser. WTF?
