             Summary: ValueError in RCMES test
                 Key: CLIMATE-822
                 URL: https://issues.apache.org/jira/browse/CLIMATE-822
             Project: Apache Open Climate Workbench
          Issue Type: Bug
            Reporter: Ibrahim Jarif
            Priority: Critical
             Fix For: 1.1

Loading AFRICA_KNMI-RACMO2.2b_CTL_ERAINT_MM_50km_1989-2008_tasmax.nc into an OCW Dataset Object
KNMI_Dataset.values shape: (times, lats, lons) - (240, 201, 194) 

Working with the rcmed interface to get CRU3.1 Daily-Max Temp
We are going to use the Model to constrain the Spatial Domain
The KNMI_Dataset spatial bounds (min_lat, max_lat, min_lon, max_lon) are: 
(-45.7599983215332, 42.2400016784668, -24.639999389648438, 60.279998779296875)

The KNMI_Dataset spatial resolution (lat_resolution, lon_resolution) is: 
(0.43999863, 0.44000053)


Calculating the Maximum Overlap in Time for the datasets
Overlap computed to be: 1989-01-01 to 2008-12-01
We are going to grab the first 3 year(s) of data
Final Overlap is: 1989-01-01 to 1992-01-01
Fetching data from RCMED...
CRU31_Dataset.values shape: (times, lats, lons) - (37, 176, 170)
KNMI_Dataset.values shape: (times, lats, lons) - (240, 201, 194)
Our two datasets have a mis-match in time. We will subset on time to 3 years

CRU31_Dataset.values shape: (times, lats, lons) - (37, 176, 170)
KNMI_Dataset.values shape: (times, lats, lons) - (37, 201, 194) 

Temporally Rebinning the Datasets to a Single Timestep
KNMI_Dataset.values shape: (201, 194)
CRU31_Dataset.values shape: (176, 170)

Spatially Regridding the CRU31_Dataset...
Final shape of the KNMI_Dataset:(1, 176, 170)
Final shape of the CRU31_Dataset:(1, 176, 170)
