RC 4141 Changes from RC 4140
- The snow 24 hour accumulation is now reset to zero after the "snow hour" processing is complete and the extra log file written.
This means that the true final daily total will be available in the first record of the following snow day the same as the daily rainfall total in the monthly log file - Change in laser/snow depth logging to add extra details and to log on values changing as well as once a minute
- New snow depth filtering mechanism implemented. This is a three-stage filter...
-
Stage 1 applies a median filter to the raw values - you can specify the length of time in minutes for the median values. This is good for filtering out sudden spikes.
-
Stage 2 applies a clip to the output of the median filter. The clip limits the step size of the increase/decrease of the output of stage 1 to the value you specify
-
Stage 3 applies an Exponential Moving Average filter to the output of stage 2. This is essentially time based smoothing
-
The default values are:
Laser Units mm cm inch median (mins) 10 clip (laser units) 1.0 0.1 0.04 EMA time (mins) 12.0 -
Note you can effectively disable any stage by setting: median=1, or clip=10, or EMA=1
-
Increasing the filtering also delays the value being updated. The approximate delay is median/1.5 + EMA time/1.5. The defaults will give a 10-12 minute lag
-
You can edit the new smoothing filter values in the Calibration Settings screen
-
Suggested starting Minimum Increments for the new filter: 2-5 mm, 0.2-0.5 cm, 0.08-0.2 inches
