      These simple observations indicate that basic information from SeaWiFS spectral data should be sufficient to qualitatively distinguish water types identified over the studied area. A characterization of the main surface bodies in the area has been achieved. Vol. SeaWiFS prelaunch radiometric calibration and spectral characterization.

    -board calibration devices. - Vicarious calibration with in -situ measurements - Trending using crosscalibration to SeaWiFS (to MODIS Aqua after ) - COTCS prelaunch polarization characterization incomplete (only part of optical path) - Preliminary estimates indicate polarization sensitivity of 5 %. The SeaWiFS on-orbit calibration strategy uses monthly lunar observations to monitor the long-term radiometric stability of the instrument and applies daily observations of its solar diffuser (an aluminum plate coated with YB71 paint) to track the short-term changes in the instrument response.

    paper presents the MODIS Aqua results using the latest MODIS and SeaWiFS calibration improvements. The most signi cant correction is needed at nm starting in 2. STANDARD MODIS CALIBRATION AND CHARACTERIZATION METHODS The standard MODIS calibration equation[5] uses the calibration coef cient m 1 to describe changes in the radiometric sensi-. •Many of these effects can only be characterized pre-launch but post-launch calibration if often required for gain calibration •Both pre-launch characterization and on-orbit calibration are critically important Guidelines for Radiometric Calibration of Electro-Optical Instruments for Remote Sensing.

The complete set of gain responses has been published in the SeaWiFS Prelaunch Radiometric Calibration and Spectral Characterization Report in the SeaWiFS Project Technical Report Series.

The instrument has scanning mechanisms to drive an off-axis folded telescope and a rotating half-angle mirror that is phase-synchronized with, and rotating at. calibration of the instrument, and a further discus-sion, along with bilinear gains, is given in Section 3.A.

Additional details on the design of SeaWiFS are given in Barnes and Holmes.8 3. Direct Calibration The radiometric model for SeaWiFS is designed to incorporate the laboratory calibration of the instru-ment with on-orbit changes over time.

SeaWiFS technical report series. Volume SeaWiFS prelaunch radiometric calibration and spectral characterization Based on the operating characteristics of the Sea-viewing Wide Field-of-view Sensor (SeaWiFS), calibration equations have been developed that allow conversion of the counts from the radiometer into Earth-existing radiances.

These radiances are the geophysical. SeaWiFS Calibration: the Ocean Color Cal/Val Paradigm • Pre-launch laboratory (spectral, spatial, and radiometric), SRR, PDR, CDR • Pre-launch calibration and characterization • Post-launch validation • Establishing good communications is critical.

SeaWiFS chlorophyll-a concentrations around the Hawaiian Islands on February 5, MOBY is the Marine Optical Buoy used for the vicarious calibration of SeaWiFS.

Areas of clouds and land are true color composites of the total observed radiances at nm, nm, and nm. The characterization of integrating spheres and blackbodies using SI traceable standards at NIST has been the hallmark of interaction between NIST and NASA for many of the EOS instruments including the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) and the Moderate Resolution Imaging Spectroradiometer (MODIS) pre-launch sensor level calibrations.

Out-of-band response (out-of-band light leaks) is a significant uncertainty factor in multi-spectral remote sensing instruments radiometric calibration.

In this paper, a method using a spectrum-tunable reference light source (STIS) which possess new functions of continuous and discrete spectral coverage to measure, correct and validate the The pre-launch laboratory calibration of the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) included a system-level calibration of the onboard diffuser using an external lamp and a reference.

Chapter 1 describes the calibration and characterization of the GSFC sphere, which was used in the recent recalibration of the SeaWiFS instrument. SeaWiFS Prelaunch Radiometric Calibration and.

The Calibration and Validation Team (CVT) has three main tasks: 1) Calibration and characterization of the SeaWiFS in-strument; 2) Development and validation of the operational at-mospheric correction algorithm; and 3) Development and validation of the derived product algorithms, such.

Observations of the Moon provide a primary technique for the on-orbit cross calibration of Earth remote sensing instruments. Monthly lunar observations are major components of the on-orbit calibration strategies of SeaWiFS and MODIS. SeaWiFS has collected more than low phase angle and 59 high phase angle lunar observations over 12 years, Terra MODIS has collected more than 82 scheduled.

The calibration approach used by the SeaWiFS program, in particular the direct traceability to NIST established by the SXR, resulted in a good agreement between the prelaunch calibration and on-orbit measurements (Barnes and McClain, ).

A summary and conclusion of J1 VIIRS pre-launch radiometric and spectral performance as well as. The radiometric calibration of the Sea-Viewing Wide-Field-of-View Sensor (SeaWiFS) in the near infrared (band 8, centered on nm) is evaluated by use of ground-based radiometer measurements of solar extinction and sky radiance in the Sun's principal plane at two sites, one located 13 km off.

Various studies have estimated the radiometric calibration for the SeaWiFS nm band to be between 7% low [42] and 8% high [43]. Using aerosol information derived from CIMEL Sun photometers. Calibration and characterization of the SeaWiFS instrument requires: a) prelaunch sensor data, b) results from the instrument certification matrix, c) summaries of the instrument pre-ship review, and d) extensive visitation reports by a Project representative to Raytheon Santa Barbara Research Center (SBRC), the manufacturing site.

The spectral radiance of the sphere at these radiance levels was also measured by the The Prelaunch Radiometric Calibration of SeaWiFS from this work correspond to g 1 and the TDI set- The initial characterization and calibration of SeaWiFS was performed by the instrument's manufacturer, SBRC.Prelaunch Radiometric Characterization and Calibration of the S-NPP VIIRS Sensor It has 22 spectral bands covering the spectrum between and μm, including 15 reflective solar bands.Because a Type 1 ocean color sensor will undergo a vicarious calibration, meeting pre-launch standards becomes less crucial to the success of the mission as long as the other aspects of pre-launch characterization (spectral tests, polarization tests, etc.) and a successful on-orbit sensor stability-monitoring program are conducted.
