Currently, the MODIS instrument on the Aqua satellite has a number of broken detectors resulting in unreliable data for 1.6 micron band (band 6) measurements. Damaged detectors, transmission errors, and electrical failure are all vexing but seemingly unavoidable problems leading to line drop and data loss. Standard interpolation can often provide an acceptable solution if the loss is sparse. In...

MODIS, the Moderate Resolution Imaging Spectroradiometer (MODIS), is scheduled for launch in late 1998 or 1999 aboard the first Earth Observing System (EOS) platform. Global, daily snow-cover maps with a spatial resolution of 500 meters will be produced from MODIS data using a fully-automated and computationally-frugal snow-mapping algorithm. Recently, modifications to the original snow-mapping...

The MODIS Land team is producing a suite of global land products whose uncertainty will be estimated through validation activities. The MODIS Land team will base its validation work on the comparison of its products to similar products derived from independent sources. The independent products will be derived from a combination of in situ data and imagery from airborne and spaceborne sensors. S...

This paper describes a technique for restoring and reconstructing a scene from overlapping images. In situations where there are multiple, overlapping images of the same scene, it may be desirable to create a single image that most closely approximates the scene, based on the data in all of the available images. For example, successive swaths acquired by NASA’s moderate imaging spectrometer (MO...

Vertical sounding measurements within stratocumuli during two aircraft field campaigns, Marine Stratus/stratocumulus Experiment (MASE) and Physics of Stratocumulus Top (POST), are used to validate Moderate Resolution Imaging Spectroradiometer (MODIS) cloud optical thickness (COT), cloud liquid water path (LWP), and cloud effective radius (re). In situ COT, LWP, and re were calculated using 5 m ...

Monthly measurements of leaf area index (LAI) and the fraction of absorbed photosynthetically active radiation (fAPAR) taken at approximately monthly intervals were collected along three 750 m transects in a Kalahari woodland near Mongu in western Zambia. These data were compared with MODIS NDVI (MOD13, Collection 3) and MODIS LAI and fAPAR products (MOD15, Collection 3) over a 2 year period (2...

The aims are to validate and assess the performances of MODIS gross primary production (MODIS-GPP) and evapotranspiration (MODIS-ET) products in China’s different land cover types and their sensitivity to remote sensing input data. In this study, MODIS-GPP and -ET are evaluated using flux derived/measured data from eight sites of ChinaFLUX. Results show that MODIS-GPP generally underestimates G...

A recent revision of the MODIS Land-Surface Temperature Algorithm Theoretical Basis Document (LST ATBD) was completed in April. A paper on the vicarious calibration of MODIS Airborne Simulator (MAS) thermal infrared channels based on the MAS data and field measurement data acquired in the field campaign conducted in Mono Lake, California, on March 10, 1998, was submitted in February, revised in...

[1] This paper presents an ARTMAP neural network approach for burn detection in Moderate Resolution Imaging Spectroradiometer (MODIS) data using two methods: discrete and continuous classifications. The study area covers the states of Idaho and Montana in the United States, where extensive fire events took place during the months of July and August in the year 2000. The proposed approach differ...
