Simulations were configured with observed forcing fields from the Bondville 1998 dataset. The simulations iterated several times over one year of data; the comparisons below represent results of the fifth iteration.
In the table below, observations (when available) are in black. Noah-MP Version 1.1 results are in blue. Noah Version 3.4.1 results are in red. Click on the thumbnail images in the table below for full-sized images.

| 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 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 black) seem to have fairly low precision. | ||||
| Soil Moisture, Layer 2 (SM2) Unaveraged time series |
 |
 |
 |
 |
| Observations (in black) seem kind of suspect to me. | ||||
