2 General Approach for Ozone_cci System Verification

This chapter describes the approach taken on system and sytsem component level to integrate the ozone_cci system components and to verify them. The test assemblies and test cases are then listed and described in chapters 5 and 6.

2.1 General Verification Strategy

Figure 2-1 shows the general strategy for the verification of the whole Ozone_cci sytsem which is responsible to ensure the production of the Ozone_cci ECVs TC, NP and LP. The Ozone_cci system consists of the following specific processing systems:

Processing System BIRA

Processing System CHALM

Processing System DLR

Processing System FMI

Processing System KIT

Processing System KNMI

Processing System RAL

Processing System UBR

Processing System ULB

Processing System UofT

Processing System UofS

Each specific processing system consists of several components. Each component implements several functions and features which are needed to handle the complete production process of the ECVs. The components implement interfaces by which it is possible to exchange interface items (e.g. input products, auxiliary products).

The system components must be under version control and are tagged with configuration items. For the verification of the system suitable Test Assemblies are defined to test simple up to more and more integrated workflows. An Assembly is instanced by Assembly Versions. Each Assembly version holds the information about used versions of the involved system components.

The test coverage of an Assembly/Assembly Version is defined by the different Test Cases which are defined for an Assembly Version. The results of the test runs of an Assembly Version are documented in this document.

The verification that the system is conform to the System Requirements is reached if sufficient tests are performed successfully which cover all functions of the system.

The Test Assemblies are described in chapter 4 and the Test Cases are described with the help of tables (see chapter 5.


Figure 2-1 System Verification Approach

2.2 Technical Verification Strategy

The system is verified by the successful execution of all defined Test Cases of all defined Test Assemblies.

Regression tests are planned for the integration of the system components into the Ozone_cci system. These tests will include the whole chain of data driven.

Test runs shall be done on the basis of predefined Assembly Versions which document the following Information:

The used configuration items (versions of the used components, environment, test data etc)

Administrative test Information (Test Date, Test Persons)

One test report for the execution of the test cases of an Assembly Version reporting the test execution and the test results.

2.3 Test Environment

Each science team has its own test environment to install and test the specific processing systems.

2.4 Naming Conventions

The following naming conventions are defined for the Test Assemblies, Test Assembly Versions, Test Cases and Test Reports.

These naming conventions are not obligatory. If the teams use already other naming conventions they are free to use their own.


Test Assemblies: AS-<pp>-<aa> pp = TC or NP or LP, aa = 2 digits, e.g. AS-NP-01 Test Case: CS-<pp>->aa>-<tt> pp = TC or NP or LP, aa = the Assembly number, tt = 2 Digits for the Test Case number, e.g. TC-NP-01-01 (first Test Case of the first Nadir Profile Test Assembly)

7 Description of acceptable and stated Limitations in the Ozone_cci System

This chapter contains a description of all acceptable and stated limitations in the system and the steps taken to workaround anomalous, inappropriate, or undesired operating conditions.

7.1 Limitations in the TC Processing System

The following limitations were found in the TC processing:

1. The level-2 TC data sets rely on auxiliary cloud parameters provided by the FRESCO v6 and O2-O2 algorithms. In case of unavailability of these parameters, no total ozone retrieval is performed.

2. During two days per month, the OMI instrument switches in the so-called zoom mode, in which the spatial resolution is significantly improved with respect to the nominal mode, at cost of the spatial coverage. The level of accuracy of the total ozone columns retrieved from this specific mode with the look-up table version of GODFIT_3 is expected to be less good than for the nominal observations and are consequently not provided.

3. The TC_L3_MRG monthly mean product is not generated in case of too few data in high latitudes close to the polar night terminator

7.2 Limitations in the TTOC Processing System

The following limitations were found in the TTOC processing:

1. The level-3 TTOC retrieval depends on Cloud parameters and Total Ozone columns, if one is missing or incorrect the retrieval fails.

2. A strong dependency on the cloud product (cloud height) is observed, the dependency on the total column data is of similar magnitude.

7.3 Limitations in the NP Processing System

The following limitations were found in the NP processing:

1. Processing capability at the CEMS facility can be variable. We have between 300 and 2000 nodes available to use at any one time but is a shared facility and therefore processing time is dependent upon the level of community use

2. No limitations were found during the processing of IASI test data

7.4 Limitations in the LP Processing System

The following limitations were found in the LP processing:

Verification report for SCIAMACHY is presented in the Drift and Bias Analysis

Tests performed for all LP Systems:


1. For most of the products, the processing time is within couple of hours. Exceptions are dense samplers like MLS, SCIAMACHY and LNTOC from SCIA SCIA, which takes 45 days, 10 days and 7 days respectively. Especially for MLS there might be a risk of delivery delay on time for reprocessing.

Test has been successfully performed for the additional US sensors: SABER, HALOE, and SAGE II. The issues are summarized in 8.4.


8 Verification Summary

8.1 Verification Summary for TC

During the first phase of the project, processing tests have been successfully passed for the three instruments GOME, SCIAMACHY and GOME-2 and consisted in generating one month of L2 total ozone data for each of these instruments using the prototype code GODFIT v3 on a single core of a Linux machine. As the prototype code has not significantly changed since then, these tests remain valid and the results have been recalled in this document. For the processing of the OMI L1 data, a much faster look-up table version of the GODFIT algorithm has been developed. A similar verification test based on the production of one month of OMI data has been successfully carried out. The full reprocessing of the OMI sensor followed and the full OMI L2 total ozone data set has been made publicly available in Spring 2015. An interface still needs to be added to GODFIT in order to ingest OMPS L1 data. A similar verification test will be realized and reported in a future version of this document. For the L3 total ozone data from GOME, SCIAMACHY, and GOME-2 the tests carried out during the first phase of the project remain valid. A similar verification test has been carried out based on the production of one month of OMI L3 total ozone data. In the same way a verification test will be realized for the new TC_L3_MRG product.

8.2 Verification Summary for TTOC

Processing test has been performed for GOME and GOME-2 data. Both the operational DLR L2 data and the GODFIT v3 data were successfully used to generate one year of tropical tropospheric ozone data. The processing speed was independent of the input dataset. The SCIAMACHY and OMI data are not yet included in the processing. Here new interfaces are being developed and similar tests will be performed soon. After the processing of the OMI L2 GODFIT data a merged dataset is planned. The respective test results will be reported in an updated version of this report.

8.3 Verification Summary for NP

The processing of IASI test data did run without problems. Note that the time needed for this test processing concerns only one of the platforms (Metop-A). More processing time will be needed if the two platforms are considered.

8.4 Verification Summary for LP

No verification performed so far. Most of the processing of ozone limb profiles for the mentioned sensors SCIAMACHY, MLS, SAGE II; HALOE, and SABER perform within the limitation of the vertical grid resolution. Because of low vertical resolution of the CCI pressure grid the double ozone peak and maxima are missed. An example for HALOE and SABER is shown in Fig. 2. This means that tThe position of ozone peak can be shifted off to higher or lower altitudes or missing and interpolating and the missing the double ozone peaks due to interpolation. However this is accounted in the error budget.
