WHM observations where mismatch of climr vs BGC require review

[whmacken]

Various issues where climate summaries by BGC indicate potential problems - either in climr or in BGC mapping

1. ICHmm in Robson Valley has very low CMD.total. It's likely that the rainshadow of the Premier range is not captured.
2. Coast transition subzones like IDFdc have lower CMD than expected. Suspect that rainshadow effect in model is not sufficient
3. CMD calculation. Proper balance of temp vs precip in equation? Cold dry subzones vs warm wet subzones = same CMD. Not ecologically equivalent.
