MOPITT Product Descriptions
T (Thermal or TIR): Uses the instrument's thermal infrared channels and is most sensitive to CO in the upper troposphere. Products are considered the most stable with fewer random errors due to geophysical noise.
N (Near-IR or NIR): A measure of the total column of CO and uses reflected solar light and are only available during the daytime portion of the orbit over land.
J (Joint Products): Combines Thermal and Near-IR channels.
Users should be very cautious in using the N and J products, and are encouraged to collaborate with MOPITT science team members to exploit it properly.
Compared to earlier TIR-based MOPITT products, this product exhibits larger random errors and may require significant spatial and/or temporal averaging.
