These large-amplitude potential spikes are supported by trapped electron populations. For parameters of low and mid-altitude auroral passes with gyro-to-bounce frequency ratios significantly larger than unity, the potential spikes are very resilient, while for lower magnetic fields, at ratios below unity, they develop unstable undulations in the transverse direction. The evolution of the solitary structures is related to changes in the trajectories of the trapped electrons. It is shown here that the coupling of the parallel and perpendicular dynamics is stronger when the above ratio decreases, resulting in a bifurcation of trajectories. The addition of a small perturbation to the large amplitude structure leads to a very different response of the trapped electrons in the two configurations. The electron behavior reflects the lack of spike stability at small gyro-to-bounce frequency ratios.</p></div>","PeriodicalId":101026,"journal":{"name":"Physics and Chemistry of the Earth, Part C: Solar, Terrestrial & Planetary Science","volume":"26 1","pages":"Pages 165-168"},"PeriodicalIF":0.0,"publicationDate":"2001-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S1464-1917(00)00103-3","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81306729","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The influence of precipitation time-variability and road pavement geometry on the water film dynamics is investigated using an experimental monitoring station installed on a mountain road which is prone to heavy storms. The monitoring station is composed by a road portion, a rain gauge and a video-camera automatically activated during intense rainfall. The investigation is based on the digital analysis of the recorded images between summer and autumn 1999. The water film surface irregularities, due to the raindrop impact with the surface and to the presence of roll waves, are studied. The first results are relative to the analysis of the roll-waves dynamics, as they are prevalent in terms of visible effects during the periods of intense rainfall. The digital analysis of the image sequences allows estimating direction and speed of the wave propagation with variable precision due to different light conditions. Using empirical relationships derived from laboratory experiments (Caporali <em>et al.</em>, 2000b), and a high-resolution Digital Terrain Model (DTM) of the road surface, depth and discharge of the water film in the maximum local slope direction are investigated.</p></div>","PeriodicalId":101026,"journal":{"name":"Physics and Chemistry of the Earth, Part C: Solar, Terrestrial & Planetary Science","volume":"26 10","pages":"Pages 717-722"},"PeriodicalIF":0.0,"publicationDate":"2001-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S1464-1917(01)95015-9","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79044592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

SCIAMACHY operates in eight channels covering the UV, the visible and two infrared regions. Recent developments in the testing of the instrument now enable not only the full use of channel 1 (240 nm–314 nm) at a required high level of performance but in some special cases its extension to 220 nm. This instrumental improvement allows new objectives to be addressed in the upper stratoosphere, on top of the already proposed mesospheric and thermospheric investigations of nitric oxide. Simulations show the instrument capabilities for these studies. These NO observations will be performed in solar occultation, lunar occultation and nadir. Previous NO results are reviewed with an emphasis on results obtained by the infrared solar occultation technique as exemplified by the SPACELAB grille spectrometer and other instruments. The capabilities of SCIAMACHY for mapping the total column of upper atmospheric NO is investigated as well as possibilities to infer NO vertical distribution and transfer properties between the different atmospheric regions.</p></div>","PeriodicalId":101026,"journal":{"name":"Physics and Chemistry of the Earth, Part C: Solar, Terrestrial & Planetary Science","volume":"26 7","pages":"Pages 545-548"},"PeriodicalIF":0.0,"publicationDate":"2001-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S1464-1917(01)00044-7","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73286845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, this solution seems to be still far away from implementation; whereas other methods based on sounding rocket flights and measurements from the ground present problem like the sporadicness and/or scarce spatial coverage of the observations. As an alternative to these previous approaches this paper studies the possibility of using a satellite on a very eccentric orbit (e ≈ 0.5) as a possible alternative, more rewarding in terms of cost and reliability. In addition to the altitude, the Earth's Thermosphere characteristics depend mainly on the latitude and solar local time. Thus we intend to study the rate of variation of these terms as function of the rate of variations of right ascension of the ascending node and perigee argument, in order to evaluate the time necessary for meeting our requirements in terms of latitudinal and solar local time coverage. Then, the characteristics of a suitable orbit in terms of semi-major-axis and inclination can be determined according to the type of study to be performed. Furthermore we intend to analyze the possible difficulties that could arise when the full separation of any effect is afforded with the aim of selecting the orbit, for a single satellite or for a constellation of small satellites, able to minimize the limitations in the spatial and temporal effects separation.</p></div>","PeriodicalId":101026,"journal":{"name":"Physics and Chemistry of the Earth, Part C: Solar, Terrestrial & Planetary Science","volume":"26 4","pages":"Pages 265-273"},"PeriodicalIF":0.0,"publicationDate":"2001-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S1464-1917(00)00119-7","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80230018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
