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 Information


Project Title: GOZCARDS: Global Ozone Chemistry and Related trace gas Data Records for the Stratosphere

PI Name: Lucien Froidevaux

Project Description: GOZCARDS (Global OZone Chemistry And Related trace gas Data records for the Stratosphere) refers to a commonly-formatted Earth system data record (ESDR) for stratospheric composition, of high relevance to the issue of ozone decline and recovery. High-quality long-term ozone and related trace gas data records are needed to (a) evaluate and understand composition changes in the atmosphere and (b) constrain model representations of atmospheric dynamics and photochemistry.

The datasets are drawn from zonal mean satellite-derived global stratospheric composition measurements from 1979 onward, as well as from GMAO MERRA (meteorological analyses) for temperature. The satellite-based abundance measurements come from high quality data from past missions (e.g., SAGE, HALOE data) as well as ongoing missions (ACE-FTS and Aura MLS). The planned data records are provided as time series zonal average profiles (versus pressure) as a function of latitude, for temperature and the following species: hydrogen chloride (HCl), ozone (O3), water vapor (H2O), chlorine monoxide (ClO), nitric acid (HNO3), methane (CH4), hydrogen fluoride (HF), nitrous oxide (N2O), nitrogen dioxide (NO2), and nitrogen oxide (NO). Additional "derived" data records, obtained via a constrained photochemical model, are planned for active chlorine (ClOx) and odd nitrogen (NOx). Data records are zonal means on a common grid, with time resolution of 1 month (and 1 day when possible, i.e. for MLS data).

The establishment of such commonly-formatted data records involves careful screening and production of "source" datasets (zonal means), the evaluation of offsets (biases) between various datasets, and assessments of spatial and temporal consistency. We provide public access to both the source data records and merged data records (if a merged product is produced) in yearly netCDF files, along with a ("README") users guide and documentation of methodology and sample results.
