Error { code = 400; message = "ERROR: Your have asked this service to utilize the DAP2 data model to process your request. Unfortunately the requested dataset contains data types that cannot be represented in DAP2. There are 13 incompatible variables and/or attributes referenced in your request. Incompatible variables: Int8 mask[time=1][lat=17999][lon=36000] Int8 mask@_FillValue Int8 mask@valid_min Int8 mask@valid_max Int8 mask@flag_masks Int8 sea_ice_fraction[time=1][lat=17999][lon=36000] Int8 sea_ice_fraction@_FillValue Int8 sea_ice_fraction@valid_min Int8 sea_ice_fraction@valid_max Int8 dt_1km_data[time=1][lat=17999][lon=36000] Int8 dt_1km_data@_FillValue Int8 dt_1km_data@valid_min Int8 dt_1km_data@valid_max You may resolve these issues by asking the service to use the DAP4 data model instead of the DAP2 model. - NetCDF If you wish to receive your response encoded as a netcdf file please note that netcdf-3 has similar representational constraints as DAP2, while netcdf-4 does not. In order to request a DAP4 model nectdf-4 response, change your request URL from dataset_url.nc to dataset_url.dap.nc4 - DAP Clients If you are using a specific DAP client like pyDAP or Panoply you may be able to signal the tool to use DAP4 by changing the protocol of the dataset_url from https:// to dap4:// - If you are using the service's Data Request Form for your dataset you can find the DAP4 version by changing form_url.html to form_url.dmr.html"; }
