Comparison -- Version 3.3 with Version 3.2

Bondville, 1998 dataset

Simulations were configured with observed forcing fields from the Bondville 1998 dataset.



In the table below, observations (when available) are in blue. Version 3.2 results are in magenta. Version 3.3 results are in dark red. Click on the thumbnail images in the table below for full-sized images.

For the Version 3.2 job, a bug fix has been applied which corrects the order of IZ0TLND and SFCDIF_OPTION in a subroutine argument list.

Average diurnal cycle
Soil Temperature, Layer 1 (ST1)

Average diurnal cycle
We are comparing the temperature observation at 4 cm below the surface, to the Noah layer temperature from surface to 10 cm.
Soil Temperature, Layer 2 (ST2)

Average diurnal cycle
We are plotting the observations at 32 cm below the surface, and the Noah layer from 10 to 40 cm below ground (i.e., centered at 25 cm below ground).
Soil Temperature, Layer 2 (ST2)

Unaveraged time series
Plotting the observations at 32 cm below the surface, and the Noah layer from 10 to 40 cm below ground (i.e., centered at 25 cm below ground).
Soil Temperature, Layer 3 (ST3)

Unaveraged time series
Comparing observations at 64 cm below ground to the Noah layer 40 to 100 cm below ground (i.e., centered at 70 cm below ground).
Soil Moisture, Layer 1 (SM1)

Unaveraged time series
Observations (in blue) seem to have fairly low precision.
Soil Moisture, Layer 2 (SM2)

Unaveraged time series
Observations (in blue) seem kind of suspect to me.
Soil Moisture, Layer 3 (SM3)

Unaveraged time series
Observations (in blue) seem suspect to me.
