MOPITT Product Descriptions

MOPITT Product Descriptions


(Beta or Non-Beta):  The differences between Beta releases of MOPITT data and non-Beta releases are explained in more detail

                                    in "Beta or Not Beta Product Descriptions" (PDF).


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.



Level 3 is either a daily or monthly gridded version of Level 2 Data Products



*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.
