First, when you say you are not able to extract the values, do you mean you get an error message, or you don't get the values you expect? Please be more specific if you can.</div>
<div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default" style="font-size:small">Also, I don't understand what's going on in your code. It looks like you are reading variables off a group of files (opened with "addfiles"), and then attaching lat and lon coordinate arrays to them afterwards. Did you first check to see if the variables maybe already have coordinate arrays when you read them off the file? You can verify this with:</div>
<div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default" style="font-size:small">printVarSummary(u1)</div><div class="gmail_default" style="font-size:small">printVarSummary(v1)</div><div class="gmail_default" style="font-size:small">
<br></div><div class="gmail_default" style="font-size:small">right after your "addfiles" call.</div><div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default" style="font-size:small">
The other possibility is that your data is "curvilinear" and hence you have 2D arrays of lat and lon, and not 1D arrays. If your lat/lon are 2D, then you can't attach coordinate arrays, and you won't be able to use coordinate subscripting via the "{" and "}" syntax.</div>
<div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default" style="font-size:small">Instead, you will need to use the function "getind_latlon2d":</div><div class="gmail_default" style="font-size:small">

<div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default" style="font-size:small">If you continue to have problems with this, please provide more information, and also call "printVarSummary" on your data variables (u1, v1, lat, lon) and include this output so we can see what kind of data you have.</div>

<p>Hi </p>
<p><br>
</p>
<p>I am intending to extract the wind speed at a particular level and latitude longitude .There are 159 time instances in about 159 files and I am trying to get the wind speed out at all those time instances at the particular latitude and longitude shown in
the code attached .Kindly suggest for any chages if required. Till now I am not able to extract the correct values.
