Detection of Daytime Arctic Clouds using MISR and MODIS Data
Amongst the 36 spectral radiances available on the Moderate Resolution Imaging Spectroradiometer (MODIS) seven of them are used operationally for detection of clouds in daytime polar regions. While the information content of clouds inherent in spectral radiances is familiar, the information content of clouds contained in angular radiances (i.e., radiances emanating to space from the same object...
متن کاملDaytime Arctic Cloud Detection based on Multi-angle Satellite Data with Case Studies
Global climate models predict that the strongest dependences of surface air temperatures on increasing atmospheric carbon dioxide levels will occur in the northern high latitudes of Alaska, Greenland, and eastern Siberia (Giorgi and Bi, 2005). A systematic study of these dependences requires accurate Arctic-wide measurements, especially of cloud coverage as gains or losses in cloud coverage can...
متن کاملSynchronous NmF2 and NmE daytime variations as a key to the mechanism of quiet-time F2-layer disturbances
The observed NmF2 and NmE variations were analyzed for the periods of positive and negative quiet-time F2-layer disturbances (Q-disturbances) observed in the midlatitude daytime F2-layer to specify the mechanism of their origin. The noontime δNmF2 and δNmE deviations demonstrate a synchronous type of variation which can be explained by vertical gas motion in the thermosphere. This neutral gas m...
متن کاملQuiet healing.
Both physicians and patients want deeply healing doctor-patient relationships. Too often, though, the ever-expanding demands of medical practice combine with the defenses of the patient to create doctor-patient isolation. Eastern and Western cosmologies and traditions may encourage different approaches to human interaction and healing. At times, probing the patient with more questions may open ...
متن کاملQuiet caring.
D URING A WALK ABOUT THE ONCOLOGY unit where I was receiving antibiotics for pneumonia, I encountered an elderly woman, her arm splinted and wrapped by a sling and burdened by intravenous and oxygen tubing. She was slowly and painfully making her way to the family lounge with her nurse and daughter. I helped them into the room, and then we all sat down. I asked her about her arm. She told me th...
