Monthly MODIS-GOCART Aerosol Optical Thickness Intercomparison
Beta Version
Home
Comparison of Monthly Level-3 Aerosol Parameters from Measurements and Model. Includes measurements from Terra and Aqua MODIS, Terra MISR and Aura OMI, as well as GOCART model data. It is suggested that Users note the Collection Version of the Science Parameters that can be seen in the third column of the parameter blocks below.

Notes:
'Analyis Options' allow you to visualize of the following analysis (or data) types:
Parameter:
original data of the selected parameter
Climatology:
pre-generated monthly climatology of the selected parameter(s). To discover how the climatology was created, click the 'Climatology Info' button to display the climatology column in the parameter table below, then click on the climatology product link.
Note
that all of the climatology products are
pre-generated
.
Anomaly:
monthly anomaly of the selected parameter(s):
Xa ( i ) = X (i ) - Xm ( i )
where:
i
denotes month (1, 2, ... , 12),
Xa(i)
represents the anomaly data for the month
i
,
X(i)
is the original data of the month
i
,
Xm(i)
is the monthly climatology data for the month
i
.
Note:
Time or spatial averages are performed on the anomaly data. For example, when time average is performed, such as service: Lat-Lon map, Time-averaged, the system calculates monthly anomaly first and averages the monthly anomalies for each grid point. Similarly, when spatial average is needed, such as time series plot, the system calculates monthly anomaly first and then do spatial average for each month.
Parameters that do not have associated climatology are disabled (you won't be able to select them) when either the climatology or anomaly analysis is selected
You must select a parameter (left-most column checkbox in the tables below) in order for its climatology or anomaly to be plotted.
