[gradsusr] Conditional summing (sum if) in grads
<br><br><blockquote class="mori" style="margin:0 0 0 .8ex;border-left:1px solid #CCC;padding-left:1ex;"><div>Dear Colleges,</div><div> </div><div>I have high-frequency (1-min) model output on 1x1 km resolution grid for forecasted 2 meter temperature and precipitation amount over 24 h simulation period. I want to calculate total frozen precipitation as a sum of forecasted precipitation when 2 meter temperature was below 0 degree Celsius. Can I use s conditional summing (sum if) and sum my precipitation variable by time if my temperature variable was below 0?</div><div> </div><div>Kind regards,</div><div>Artur</div><div> </div>
