Six years of Nimbus-7 Scanning Multichannel Microwave
Radiometer (SMMR) data from 1979 to 1984 are recalibrated
at the radiometric level. New statistical techniques are
developed to quantify the temporal and orbital data errors
and to generate numerical corrections for brightness temperatures
prior to estimation of geophysical parameters.

The effects of trade liberalization and trade integration can be seen in many
developing countries around the world. While freer trade can be said to create benefits
from efficient allocation of resources, it does not ensure that gains from trade will be

We address the endogeneity of border enforcement with an instrumental variables strategy based on administrative delays in budgetary allocations for border security. We find that 1,000...
The North Unit irrigation District of Central Oregon,
a water project developed under the guidelines of the
Bureau of Reclamation, is characterized by limited water
and the need for efficient utilization and control of the
irrigation system. To manage the limited water resource,
irrigators need a timely and economical method...
The need to preserve Oregon's estuaries has been expressed
through the Land Conservation and Development Commission's Estuarine
Resources Goal 16. The first use of the mitigation guideline set forth
in this goal is in the Coos Bay estuary. The proposed North Bend
Airport runway extension will fill 32 acres (13...
Four new species of fossil mermithids (Nematoda: Mermithidae) are described from amber: Heydenius arachnius n. sp. from a spider (Arachnida: Araneae) in Dominican amber, Heydenius phasmatophilus n. sp., from a walking stick (Phasmatodea: Phasmatidae) in Baltic amber, Heydenius podenasae n. sp. from a moth (Lepidoptera) in Baltic amber and Heydenius...
