[rimprona] RIMpro anomalies

[Marc Trapman]

Hi,

RIMpro values from the past should not change as the weather-data are fixed in te file, unless you change parameters: either biofix or model parameters.

In the MeteoBue calculations the LW values are the results of LW calculations of 10 random leaves. As these calculations are re-run over the season, also over the past data,  minor changes could occur as rounding the the results of these 10 leafs.

I have been working on the Leaf-wetness model that is applied on the MeteoBlue data as sometimes the leaf-wetness on one or two of the 10 leafs got stuck and leafs stay wet over several days. 
I just have put a debugged version now on the system and will follow this closely the coming days.
Can you please check if leaf-wetness as generated by the LW model for the MeteoBlue data is correct now ?


With kind regards, 
Marc

So far, the MeteoBlue forecast seems to be predicting longer wetting periods and/or warmer temps than the yr.no <http://yr.no/> forecast, but the yr.no <http://yr.no/> forecast seems to be closer to reality as measured by our on-ground NEWA station.  Thus, for the next two days, the MeteoBlue system is predicting a RIM event that will reach 482 whereas the yr.no <http://yr.no/> system is predicting an event that will reach a RIM value of only 11.  I have not taken time to determine if the major difference between the two systems is wetting during or temperature, but I believe it is wetting duration.

I had assumed that if I checked the recorded RIM value for yesterday, that value would remain constant throughout the rest of the season because that weather event is now history. (In fact I have been recording the RIM values of the previous day every morning.)  What I am finding, however, is that (at least with MeteoBlue) the history also changes over time.  For example, when I checked the Venturia table yesterday at 5 pm, the MeteoBlue table said that the RIM value for Sat, 9 April, was 10. When I checked this morning, the history for Sat, 9 April was showing a RIM value of 1166 and the value for Friday, 8 April (which had previously been 1) was now shoing 1079.  Thus, MeteoBlue seems to be generating major RIM events after the fact when none are showing at the time that they should be appearing as part of on-going weather systems.
