چکیده

Ozone profiles retrieved from limb scattering measurements of the SCIAMACHY instrument based on the satellite ENVISAT are compared to ground-based low altitude resolution remote sensors. All profiles are retrieved using optimal estimation. Following the work of Rodgers and Connor (2003) the retrievals of the ground-based instruments are simulated using the SCIAMACHY retrieval. The SCIAMACHY results and the results of the ground-based microwave radiometer in Bremen and Ny A° lesund agree within the expected covariance of the intercomparison.

Studying Envisat Attitude with Sciamachy Limb-scatter Measurements

High pointing accuracy is a prime prerequisite of high quality remote sensing of atmospheric constituents using limb viewing instruments. SCIAMACHY limb measurements were affected by limb tangent height errors of up to 3 km during the initial phase of the Envisat mission. These errors were caused by inaccurate satellite attitude information and possibly an instrument misalignment. Retrieval of ...

A compact receiver system for simultaneous measurements of mesospheric CO and O3

During the last decades, ground-based microwave radiometry has matured into an established remote sensing technique for measuring vertical profiles of a number of gases in the stratosphere and the mesosphere. Microwave radiometry is the only ground-based technique that can provide vertical profiles of gases in the upper stratosphere and mesosphere both day and night, and even during cloudy cond...

SP-531 Envisat Validation Workshop

In order to assess the level-2 data retrieval accuracy of selected trace gases (O3, NO2, H2O) from SCIAMACHY and MIPAS, which are part of the atmospheric instrumentation on the recently launched ENVISAT satellite, operational and some scientific products are validated by comparison with other space borne instruments (GOME, HALOE, SAGE II, POAM III). First results of these satellite intercompari...

Quality assessment of O3 profiles measured by a state-of-the-art ground-based FTIR observing system

Ground-based Fourier Transform Infra-Red (FTIR) measurements are an important component of the global atmospheric monitoring system. Their essential role in validating satellite measurements requires a precise documentation of their quality. Here we present an extensive quality documentation of ground-based FTIR O3 profiles. This is done in the form of theoretical and empirical error estimation...
