Data quality is affected in several ways. They are:
Once a new set of data is processed, several validity checks are made to ensure the data quality. The hypothesis regarding the physical phenomena based under which the algorithm of data retrieval is designed, is also checked for accuracy.
Original data is always protected since only authorized personnel have access to the original data.
OMI have several products of significant importance for climate studies. OMI products can be analyzed in local, regional and global scale to understand the trend of greenhouse gasses. OMI data can be used with meaurements by other satellites for validity checks. Atmospheric chemistry models and global circulation models can use OMI data for comparative analysis and understanding of modeling formulations.
OMI data is accurate under the conditions of the assumptions used for data retrieval. As the scientific knowledge is maturing everyday, OMI scientists are always alert to implement a better methodology that is available for data retrieval. Algorithms are timely updated. Attempts are made to minimize calibration errors by checking instrument conditions from time to time.
