Data access for the SMILES products

SMILES Level 2 research product (version 3.0.0) is available to collaborators with NICT. The product is not open to the public at this moment, because the product is still under the validation phase and the interpretation of the non-sun-synchronous orbital data of photochemistry-related species requires special treatment that is not well documented yet.
