<body class='hmmessage'><div dir='ltr'>Hello,<br><br>I am using wrf_user_getvar in NCL 6.3.0 to calculate cloud top temperature (CTT) from WRF outputs. The spatial distribution of CTT looks ok. But the values are between -210K and -190K. A sample image is enclosed. Does anyone have any suggestion?<br><br>Thanks,<br><br>-Longtao <br>                                            </div></body>
