NASA, through its Earth Science Data Systems, supports the NASA Earth Science research community by providing Earth science data products and services driven by NASAs Earth Science goals. NASAs Earth Science Program is dedicated to advancing Earth remote sensing and pioneering the scientific use of satellite measurements to improve human understanding of our home planet, in order to inform economic and policy decisions and improve operational services of benefit to the Nation. Through the MEaSUREs Program, NASA is continuing its commitment to expand understanding of the Earth system using consistent records. NASA has begun to deploy new types of sensors to provide three-dimensional perspectives of Earths atmosphere and surface. Emphasis is on linking together multiple satellites into a constellation, developing the means for using a multitude of data sources to form coherent time-series, and facilitating the use of extensive data in the development of comprehensive Earth system models.
As part of the ROSES-2006 announcement, MEaSUREs proposals were solicited to focus on the creation of Earth System Data Records (ESDRs), including Climate Data Records. An ESDR is defined as a unified and coherent set of observations of a given parameter of the Earth system, which is optimized to meet specific requirements for addressing science questions. These records are critical for understanding Earth System processes; for the assessment of variability, long-term trends, and change in the Earth System; and for providing input and validation means to modeling efforts. The solicitation resulted in the selection in October 2007 of 30 projects for funding.

Project Title: Creating a Long Term Multi-Sensor Ozone Data Record
PI Name: Richard McPeters
Project Description: The proposed research is for a five year effort to produce long term ozone data records by merging data from multiple instruments. The ultimate goal is an ozone Earth Science Data Record (ESDR) - a consistent, calibrated ozone time series that can used for trend analyses and other studies. Both total column ozone and ozone vertical profile data sets will be produced, and we expect records at various spatial/temporal resolutions will be necessary to meet different research requirements. As one of the first groups to implement "missions to measurements" the TOMS team at Goddard Space Flight Center has created the total ozone merged ozone data record (MOD) by consistently combining total column ozone data from TOMS/OMI and SBUV instruments. We will expand this product, adding data from three additional instruments. Data from GOME (1995-2003) on ERS-2 will provide coverage in periods when there are gaps or data quality issues in the TOMS and SBUV data records. Data from the recently launched GOME-2 instrument will be added, and data from OMPS will be included after the launch of NPP. We propose to concentrate most of our efforts on producing an ozone vertical distribution data set. We will merge profile data from various instruments, including SBUV(/2), UARS and AURA MLS, Sciamachy, GOME-1 and GOME-2. This proposal will support preparation of data from the different instruments for inclusion in the merged ozone data time series. We will also consider processing the GOME and OMPS spectral data with the same algorithm used for TOMS and SBUV in order to ensure consistency.
