Hello,
<div class=""><br class="">
</div>
<div class="">I’ve used that function a bunch. If you only want 10th and 90th percentile, you’ll want to use: </div>
<div class=""><br class="">
</div>
<div class="">qsort</div>
<div class="">Which will sort your data within a single grid cell from lowest to highest.</div>
<div class=""><br class="">
</div>
<div class="">And then grab the specific lines of code for 10th and 90th percentiles from the stat_dispersion function in:</div>
<div class="">$NCARG_ROOT/lib/ncarg/nclscripts/csm/contributed.ncl</div>
<div class=""><br class="">
</div>
<div class="">If you look at the function, you’ll see that it uses qsort, then goes step by step through calculating all the different applications.</div>
<div class=""><br class="">
</div>
<div class="">Cheers,</div>
<div class="">-Jonathan</div>

<div class="">Is it possible to use 10th and 90th percentile values only ? </div>
<div class=""><br class="">
</div>
<div class="">Also can these values be used to develop a spatial map? </div>
<div class=""><br class="">
</div>
<div class="">For example if I want to find the 10th and 90th percentile of air temperature within the urban grid cells only.</div>
