    Five southern Sierra snowmelt basins and two northern Sierra-Southern Cascade snowmelt basins were used to evaluate the effect on operational water supply forecasting from satellite imagery. Manual photointerpretation techniques were used to obtain SCA and equivalent snow line for the years to for the seven test basins using LANDSAT imagery and GOES imagery.   Historically, such fields have been constructed by a blending of in situ observations from ships and buoys and satellite infrared observations from the Advanced Very High Resolution Radiometer (AVHRR) that has been operational on NOAA satellites since November Cited by:

    Paul M. DiGiacomo, A champion for oceans and waters. 4 December - In early November, , the Group on Earth Observations (GEO) convened its annual plenary meeting, GEO Week , in Canberra, Australia. During a special awards ceremony held during GEO Week , Dr. Paul DiGiacomo (Chief, Satellite Oceanography & Climatology Division) was awarded the GEO Individual . Only observations from Earth-orbiting satellites offer such information on the global scale. In view of the importance of predictions of weather and climate to human activities, it is important to examine the progress made in the application of satellite data to weather forecasting, climate prediction and climate model validation.

    The emergence and utilization of such a radically new tool as the observation satellite will undoubtedly result in the development of applications and techniques not yet imagined or foreseeable. Satellite observations can be obtained with sufficient detail for military reconnaissance, inspection operations, mapping, and Earth-science studies. Information on snow properties is of critical relevance for a wide range of scientific studies and operational applications, mainly for hydrological purposes. However, the ground-based monitoring of snow dynamics is a challenging task, especially over complex topography and under harsh environmental conditions. Remote sensing is a powerful resource providing snow observations at a large scale Cited by: 2.

There were many problems encountered such as distinquishing clouds from snow and snow under trees. A partial solution to some of the problems involves ground reconnaissance and low air flights. This book offers a complete overview of the measurement of precipitation from space, which has made considerable advancements during the last two decades.

This is mainly due to the Tropical Rainfall Measuring Mission and a carefully maintained constellation of satellites hosting microwave sensors. Suggested Citation:"2 Core Observational Needs."National Research Council.

The Workshop on Operational Applications of Satellite Snowcover Observations at the Waystation in South Lake Tahoe, California, August, was held primarily to bring the various cooperating agencies together for an information exchange of analysis techniques, results, and problem solving.

Geostationary Operational Environmental Satellite (GOES) imager instruments provide temporally and horizontally high-resolution imager observations at visible, near-infrared, and infrared ranges of the electromagnetic spectrum.

Operational applications of satellite snowcover observations: proceedings of a final workshop sponsored by the National Aeronautics and Space Administration and the University of Nevada, Reno, and held at Sparks, Nevada, April Physical parameters – the so-called Level 1 products – are extracted from satellite observations at our headquarters, together with some geophysical parameters – the so-called Level 2 products.

The Products page has a full list of products, which primarily support the application needs for Nowcasting and Numerical Weather Prediction (NWP). Various techniques for reducing the satellite data to a form usable by the operational agencies were covered in mini-presentations by the operational satellite snow interpretive personnel.

Similar discussions were made by operational agency stream flow forecasters on how satellite-derived snow data could be incorporated into runoff forecasting methods. Barnes, J. C., and Smallwood, M.
