BACKGROUND Asthma and Allergic Rhinitis (AR) are two chronic inflammatory diseases that are often concomitant. The Control of Allergic Rhinitis and Asthma Test (CARAT) was developed to evaluate the control of these diseases from the patients' perspective. Its performance in asthma patients without AR has not been previously studied. AIM To test the hypothesis that CARAT can be used to assess ...

The philosophy underlining the Level 1 and Level 2 ASAR Wave Mode algorithms is described. The resulting products are also described including the limitations that need to be understood in order for them to be correctly interpreted. In addition, the Introduction Section contains a brief review of the history of the development of the ASAR Wave Mode products. Introduction There are 3 Wave Mode p...

Space borne radar data facilitates continuous monitoring of almost any location on the earth (limitations in polar zones) with quite low costs. Almost weather-independent operation of radar systems enables a reliable and continuous record of data from earth’s surface. In the framework of an ESA pilot project (AO335), ENVISAT polarimetric SAR data of years 2004 and 2005 are examined for their us...

Some geophysical calibration results on the level 1 ASAR WVI products are presented in the continuity of the investigations performed on the ERS1/2 SAR Wave Mode products. Investigations have been focussed on comparisons with co-located ECMWF winds. In particular, a calibration constant is tentatively derived using CMOD-IFREMER model function. Following standard azimuthal resolution losses over...

We describe validation measurements of the geometric accuracy of ASAR images, measured redundantly via independent methods. Our tests include image (IM), alternating polarisation (AP), and wide swath (WS) mode acquisitions over a variety of test sites. ASAR's slant range products (IMS/APS) require a slightly different validation methodology than ground range precision (IMP, APP) and medium reso...
