<div>Hi All:</div>
<div><br>
</div>
<div>I am working with our local NWS office and they are requesting GRIB output from our realtime WRF-ARW runs to have hourly precip accumulations.</div>
<div><br>
</div>
<div>Currently our experience with the UPP 3.0 tool has us able to output accumulated precip over the whole simulation in GRIB but not hourly. We are using the prec_acc_dt = 6 option and are receiving the normal precip accumulated outputs and also the requested
PREC_ACC_C, PREC_ACC_NC, and SNOW_ACC_NC fields.</div>
<div><br>
</div>
<div>UPP however is only accessing RAINNC and RAINC for output as per pages 7-9 for the output grib file and is displaying the total simulated accumulations. </div>
<div><br>
</div>
<div>Is there an easy patch for this, e.g., artfully using wgrib, gribw or hacking the UPP code that has given other people success in this area?</div>
<div><br>
</div>
<div>Thanks Much,</div>
<div>
