    Description: Systematic sets of ground based color and color infrared photography were presented to students in remote sensing classes to enhance their ability to interpret satellite images. Features readily apparent on computer enhanced LANDSAT images were presented simultaneously with ground based photography in the format of slide triplicates. It was hypothesized that this instructional approach would improve the students' abilities to recognize, understand and interpret ground phenomena present on remotely sensed imagery. Tests conducted in undergraduate remote sensing classes substantially upheld this hypothesis. Student image interpretive abilities were tested before and after being exposed to the ground level photography. In general, image interpretive skills of the class improved by 25%. Also, the performance of students having different academic majors varied greatly for differing types of image subjects.

    Description / Table of Contents: Zammenfassung Beobachtungen atmosphärischer Ausstrahlung (einfallende Langwellenstrahlung,L↓) wurden an der Hauptkette der Colorado Rocky Mountains, U.S. A., während des Sommers 1980 gemacht. Vier Modelle atmosphärischer Strahlung wurden ihrer Anwendbarkeit nach in einer Höhenlage von ungefähr 3500 bis 3800 m und in einer Umwelt von rauhem, gebirgigem Terrain geprüft. Die Formulierung atmosphärischer Ausstrahlung von Idso und Jackson, die lediglich von beobachteten Umwelttemperaturen abhängt, bewährte sich mindestens ebenso gut als andere, sogar in Gegenden schwierigen Zirkel-Terrains, welches durch stark variierende, topoklimatische Bedingungen charakterisiert ist. Diese Gleichung kann auf die Abschätzung der Strahlungsbilanz und der Schneeschmelze angewendet werden, wenn lediglich Temperatunnessungen zur Verfügung stehen. Die absolute mittlere Abweichung der analysierten Gleichungen bewegte sich zwischen l% und 23%.
    Notes: Summary Observations of atmospheric emittance (incoming longwave radiation,L↓) were made in the Front Range of the Colorado Rockies, U.S.A. during the summer of 1980. Four models of atmospheric emittance were tested for their utility in a high altitude (ca. 3500–3800 m) environment of rugged, mountainous terrain. The Idso and Jackson formulation of atmospheric emittance, using only observed ambient temperature, performed as well as others, even in areas of complex cirque terrain characterized by highly varied topoclimatic conditions. This equation can be of use in estimating net radiation and snow ablation where only temperature measurements are available. Absolute mean errors of equations analyzed ranged from 1% to 23%.

    Notes: Summary Present-day and 2 × CO2 regional climate impacts and the effects of local land use patterns on Cooling Degree Hours (CDHs — an energy demand parameter based on cumulative degrees of temperature above 75 °F) are investigated for the Phoenix metropolitan area in central Arizona. Approaches include: (1) the utilization of four readily available and commonly used Global Circulation Models (GCMs) to assess possible changes in climate for doubled CO2, (2) the analysis of hourly temperature data collected for one year over three different land type sites, and (3) analysis of locally collected hourly temperature data, for a typical summer day from a real-time weather and climate network, to evaluate the spatial variability of CDHs over the urban landscape. Results are discussed by showing effects at the global and urban scales. Differing surface types, and expected changes in land uses in the future, induce spatial differences of CDHs (and therefore potential energy demand) comparable to GCM projections of climate change for the region.
