The list of unavailability periods is provided in Chapter 2 together with details of any data disclaimers issued during the reporting period. Chapter 3 provides information on the background regional mission (BRM) planning. Details on the Doppler Centroid evolution are provided in chapter 4. Radiometric stability is measured by means of ASAR transponders. Detailed results are provided in chapter 5. An updated list of auxiliary data files is provided in chapters 6 and 7.

The impact of multiple TRM failures is mitigated by the generation of new antenna patterns.

An updated list of the OCM can be found at The plots of the Figure 4.1 and Figure 4.2 show the evolution of the Doppler centroid over the world for the 30 days prior to the end of the reporting period. No anomaly on the Doppler centroid distribution is noticed. 4.1 Absolute WV-IS2 Doppler Centroid Evolution (a) absolute Doppler in ascending passes

Theoretical Doppler is in red while the blue curve stands for Doppler evolution model obtained by Fourier series decomposition. Figure 4.3(b) shows a similar plot derived from global monitoring data.

Figure 4.5 shows the same information but for data acquired in GM1 mode.

14 ENVISAT ASAR MONTHLY REPORT issue 73 revision 0 page 14 of 83 5 IMAGE QUALITY AND RADIOMETRIC ANALYSIS The analysis of the ASAR transponders is used to characterise ASAR products in terms of: spatial resolution, Impulse Response Function (IRF) parameters (ISLR, PSLR, SSLR) and Absolute calibration factor. The analysis is performed for all the modes, beams and polarisations. Table 5.1 shows the relative Radar Cross Section (RCS) 1 per mode, beam and set of transponders. The values provided per sub-swath correspond to the mean absolute calibration error. Values provided per all swaths correspond to the mean error value and the corresponding standard deviation. All values are in db. In this reporting period, an improvement was made to the database for IMM, APM and WSM products by removing anomalous measurements where the default and not the true value of ISLR was used. As a result the IRF results and product counts for these product types are not in continuation with the previous report.

Num Looks Rad Res (db) Table 5.4(e): ASAR measured equivalent number of looks and radiometric resolution The noise equivalent radar cross-section (NESigma0) has been estimated using AP and IM products of low radar cross-section ocean region, as shown in Figures 5.3 & 5.4 (for pre and post Envisat orbit change in October 2010). For the post orbit change data a slight offset can be seen between the predicted and the measured NESigma0 values (this is particularly evident for IS3). The cause of this offset is currently being investigated. Apart from this offset the post orbit change measurements match the predicted values in a similar way to the pre orbit change data.

Please note that pre-launch antenna pattern where used before the first ASA_XCA_AX update. Please note that the table indicates for each beam, in which file the update took place. Any file created after this date will include that update unless a new file is specified for the beam. For instance, the pattern for IS3_SS2 VV was updated on 27 August The file created on 9 December 2003 (when the IS1 VV pattern was updated) will include the same pattern for IS3_SS2 VV as in the file of 27 August 2003, since the table does no indicate any further update for the IS3_SS2 VV pattern.
