Diurnal Temperature Range Over The United States: A Satellite View, D. Sun, R. T. Pinker, Menas Kafatos Jan 2006

Diurnal Temperature Range Over The United States: A Satellite View, D. Sun, R. T. Pinker, Menas Kafatos

Mathematics, Physics, and Computer Science Faculty Articles and Research

Diurnal temperature range (DTR) is an important climate change index. Information on this parameter comes primarily from sparse and unevenly distributed observations of shelter air temperature. In this study, five years of GOES- 8 based estimates of land surface temperature (LST) over the United States are used to evaluate DTR at high spatial resolution. The spatial and temporal patterns that emerged show a high degree of consistency with independent satellite estimates of the Normalized Difference Vegetation Index (NDVI). Specifically, the arid regions in the western and central U.S. have larger DTRs than the eastern United States or the northwest coast. …

Comparison Of The Monthly Precipitation Derived From The Trmm Satellite, D. Shin, L. Chiu, Menas Kafatos Jan 2001

Comparison Of The Monthly Precipitation Derived From The Trmm Satellite, D. Shin, L. Chiu, Menas Kafatos

Mathematics, Physics, and Computer Science Faculty Articles and Research

A comparison of monthly rainfall derived from the version 5 of TRMM Microwave Imager( TMI), Precipitation Radar (PR), TRMM Combined algorithm (TCA) and TMI-emission algorithm (TMIE) using two years (1998 to 1999) of TRMM data. was made. The global (TRMM domain, 40øN~ 40øS) average rain rates are 3.29, 2.62 and 2.93 mm/day over land and 3.02, 2.47 and 2.54 mm/day over oceans for TMI, PR, and TCA respectively. The TMIE oceanic average is 2.90 mm/day. For both the global and zonal means, the TMI rain rates are the largest and the PR estimates lowest. Regression analyses show the offsets of …
