NPP Cal/Val Study FindingsEntry ID: gov.noaa.class.NP_CONTR
Abstract: ABSTRACT: The Cal/Val Collaborative Team is responsible for the scientific oversight for sensor calibration and validation of the data products. These Cal/Val activities are conducted through four phases of the NPP Cal/Val Program. The phases are pre-launch, early-orbit checkout, intensive cal/val, and long-term monitoring. Pre-launch includes the development and test of the sensors and the ... development and verification of the algorithms. The early-orbit checkout occurs 30-100 days after launch and involves performance comparison to the pre-launch characterization results. Intensive Cal/Val lasts 18-24 months after launch and includes the calibration of the sensors and validation of the data products.
Long-term monitoring extends through the life of the sensors to ensure that data products continue to meet their performance requirements. As the Cal/Val Program progresses through these phases, science teams perform studies which provide the scientific basis for the calibration updates and validate the data products. The findings of these studies are incorporated into packages/containers which are submitted for archive. Based on the study the contents of the container can vary. Typical contents include results, documentation, detailed directions to perform the study, software, algorithms, and data or links to data required to perform the study.

Data Set ID Format:
Fees: Electronic download (FTP) of the data is free. There is a fee for copies of data on physical media. Optical disks are $25.00 per unit and magnetic tape is $100 per unit. Price does not include additional service and handling costs.
Purpose: PURPOSE: The investigator study findings are archived to provide a permanent record of the cal/val process. This record can be referenced for verification of specific mission or community requirements. These findings include sufficient details to provide an independent scientist the capability of repeating the study. Also, the techniques, algorithms, and data can be used by climate researches and cal/val teams for future sensors and products.
