I have two files I am using, one is census tract data with prj:
GEOGCS["GCS_North_American_1983",
DATUM["D_North_American_1983",
SPHEROID["GRS_1980",6378137.0,298.257222101]],
PRIMEM["Greenwich",0.0],
UNIT["Degree",0.0174532925199433]]
The other is a grid file from a model with prj:
PROJCS["airpact",
GEOGCS["GCS_Sphere_EMEP",
DATUM["D_Sphere_EMEP",
SPHEROID["Sphere_EMEP",6370000.0,0.0]],
PRIMEM["Greenwich",0.0],
UNIT["Degree",0.0174532925199433]],
PROJECTION["Lambert_Conformal_Conic"],
PARAMETER["False_Easting",0.0],
PARAMETER["False_Northing",0.0],
PARAMETER["Central_Meridian",-121.0],
PARAMETER["Standard_Parallel_1",30.0],
PARAMETER["Standard_Parallel_2",60.0],
PARAMETER["Scale_Factor",1.0],
PARAMETER["Latitude_Of_Origin",49.0],
UNIT["Meter",1.0]]

My problem is obvious, these are nowhere near the same and when I load into qgis the grid is far larger than the census tract data. I need to define them both on the same projection as the grid without ruining the census data but I am not sure how to do this. I have read several similar questions but am still lost.
I am aware that the census data is referencing lat/lon in degrees and the grid is in projected coordinates in meters, but need to somehow convert the census data to match the grid.
