<div>Dear Wang Lizhi,</div>
<div> </div>
<div>You have to make time average to convert your 6 hourly data into daily means. So use the following define function.</div>
<div> </div>
<div>define a= ave ( tmp2m, t=1, t=4)</div>
<div> </div>
<div>Then use the following command as per ur requirement</div>
<div> </div>
<div>define v=aave(a, lon=110,lon=120,lat=20,lat=30)</div>
<div> </div>
<div>other things will remain unchanged.</div>
<div> </div>
<div> </div>
<div>Regards,<br></div>
