<div dir="ltr">Hello,<div><br></div><div>I found that the CERES.HiResLandSeaMask was useful in that it includes many of the islands near the Caribbean that I was interested in. The only problem I have now is that I need to compare that lat/lon grid to the one from the International Best Track Archive for Climate Stewardship (IBTrACS) which is on a tenth degree grid. Is there a way for me to transform the CERES grid to match the IBTrACS? </div><div><br></div><div>I am attaching the code I am trying to use to get the grid I want (it is from the landsea_mask example 5). The attached pdf shows what I get for land in red on the first page and the second page is the original CERES landsea mask, so I clearly have a problem somewhere with how I am interpolating to the grid I want. </div><div><br></div><div>Thanks, </div><div>Jake</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Sun, Dec 18, 2016 at 11:45 AM, Dennis Shea <span dir="ltr"><<a href="mailto:shea@ucar.edu" target="_blank">shea@ucar.edu</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div><div><div><div><div><div><div><div>Maybe the following will help?<br><br>I have placed several land-sea masks with different resolutions at:<br><br></div>ftp <a href="http://ftp.cgd.ucar.edu" target="_blank">ftp.cgd.ucar.edu</a><br></div>anonymous<br></div>email<br></div>cd pub/shea/MASH<br></div>prompt<br></div>ls<br></div>mget *<br></div>quit<br><br>/ftp/pub/shea/MASK<br><br>-rw-r--r-- 40074 Dec 18 09:35 CERES.HiResLandSeaMask.nc.gz<br>-rw-r--r-- 300535 Dec 18 09:39 land_ocean_lake_river_mask_<wbr>pfv52.nc.gz<br>-rw-r--r-- 4558 Dec 18 09:31 lsmask.1x1_noaa_oi.nc.gz<br>-rw-r----- 16201826 Dec 18 09:31 <a href="http://lsmask-world8-var.dist5.5.nc">lsmask-world8-var.dist5.5.nc</a>.<wbr>gz<br></div><div class="gmail_extra"><br><div class="gmail_quote"><div><div class="h5">On Sat, Dec 17, 2016 at 1:07 PM, Jake Huff <span dir="ltr"><<a href="mailto:jake.huff@stonybrook.edu" target="_blank">jake.huff@stonybrook.edu</a>></span> wrote:<br></div></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div class="h5"><div dir="ltr">Hello,<div><br></div><div>I am currently trying to create a high resolution land mask to include the smaller islands in the Caribbean. I am using the mask_5.ncl example script under the masking section.

It runs correctly, but I end up with the same land mask if I plot the landmask from the basemap above. My new landmask is at the higher resolution but smaller islands are not included. I think I need to increase the resolution of the basemap as opposed to just increasing the resolution of the landmask. I was wondering how I would go about creating a 0.1x0.1 degree basemap. I need the high resolution to determine if tropical cyclones make landfall on the islands in the Caribbean, so I need to have the islands show up as land and not ocean.</div><div><br></div><div>Thanks for any help,</div><div><br></div><div>Jake</div></div>
