637! rce-comment -- tinv is the sum of all first-order-loss-rates
638! for the layer. for most layers, the activation loss rate
639! (for interstitial particles) is accounted for by the loss by
640! turb-transfer to the layer above.
641! k=pver is special, and the loss rate for activation within
642! the layer must be added to tinv. if not, the time step
643! can be too big, and explmix can produce negative values.
644! the negative values are reset to zero, resulting in an
645! artificial source.
