The Airborne Hyperspectral Scanner (AHS) and the Hyperion satellite hyperspectral sensors were evaluated for their ability to predict topsoil organic carbon (C) in burned mountain areas of northwestern Spain slightly covered by heather vegetation. Predictive models that estimated total C (TOC) oxidizable (OC) content calibrated using two datasets: a ground observation dataset with 39 samples collected field (for built AHS data), 200 TOC/OC observations predicted data). For both datasets,...
Air temperature (Ta) is a key variable in many environmental risk models and plays very important role climate change research. In previous studies we developed for estimating the daily maximum (Tmax), mean (Tmean), minimum air (Tmin) peninsular Spain over cloud-free land areas using Moderate Resolution Imaging Spectroradiometer (MODIS) data. Those were obtained empirically through linear regressions between Ta daytime Terra-MODIS surface (LST), then optimized by including spatio-temporal...
Frequent wildfires in the north-west region of Spain affect soil organic matter. Soil properties can be estimated both spatially and temporally using remote sensing. A wide range satellite airborne hyperspectral multispectral sensors are currently available. The spectral resolution varies substantially among sensors, making it difficult to identify most suitable regions for a specific application. This study aims wavelengths with greatest potential topsoil C mapping. Total (TOC) oxidisable...
The study of the thermal behavior permafrost and active layer on South Shetland Islands, in western side Antarctic Peninsula (Antarctica), has been our research topic since 1991, especially after 2006 when we established different thickness ground monitoring sites CALM GTN-P international networks International Permafrost Association. Along this period, snow cover did not change at those sites, but 2010, observed an elongation duration, with similar onset, a delay offset. Due to important...
Since 2006, our research team has been establishing in the islands of Livingston and Deception, (South Shetland archipelago, Antarctica) several monitoring stations active layer thickness within international network Circumpolar Active Layer Monitoring (CALM), ground thermal regime for Ground Terrestrial Network-Permafrost (GTN-P). Both networks were developed International Permafrost Association (IPA). In GTN-P stations, addition to temperature air, soil, terrain at different depths, snow...
We have characterized the snow albedo decay over Hurd Peninsula, Livingston Island, Antarctica, for period 2000-2016. The was obtained from MOD10A1 product of spaceborne MODIS sensor. A low-pass filter is applied to data in order eliminate short-term variations and retain seasonal variation albedo. fitted an exponential function obtain rate, duration starting date decay. On average, starts late September lasts 96 ± 20 days. Snow melting lags behind This lag due, on one hand, occurrence...
In this article, we present empirical models for estimating daily surface water vapour pressure (e0), air temperature (Ta), and relative humidity (RH) over cloud-free land areas in peninsular Spain using Moderate Resolution Imaging Spectroradiometer (MODIS) spatiotemporal variables. The were obtained validated mean, maximum, minimum e0, Ta, RH data (year 2010) from 331 ground-level meteorological stations the diurnal Terra-MODIS Spain, but methodology can easily be extrapolated used to...
The aim of this work is to investigate whether snow albedo seasonality and trend under all sky conditions at Johnsons Glacier (Livingston Island, Antarctica) can be tracked using the Moderate Resolution Imaging Spectroradiometer (MODIS) daily product MOD10A1. time span from December 2006 February 2015. As MOD10A1 has never been used in Antarctica before, we also assess performance for cloud mask. motivation need a description (including overcast days) satellite data with mid-spatial...
In this article, we present empirical models for estimating daily mean air temperature (Ta) in the Hurd Peninsula of Livingston Island (Antarctica) using Moderate Resolution Imaging Spectroradiometer (MODIS) Land Surface Temperature (LST) data and spatiotemporal variables. The were obtained validated Ta from three Spanish situ meteorological stations (AEMET stations), Juan Carlos I (JCI), Johnsons Glacier (JG), (HG), our team’s monitoring sites, Incinerador (INC), Reina Sofía (SOF), Collado...
Byers Peninsula (62°34’-62°40’S-60°54’61°13’W), 60 km2 in size, is considered one of the largest ice-free areas Antarctica. Since 2006, Spanish Polar Program has taken part a large number environmental studies involving effects climate changes, limnology and microbiology, live cycles, but not albedo. Surface albedo key physical parameters surface energy budget polar regions. Most Antarctica covered by ice sheets; only about 0.44% area permanently ice-free. However, maritime Antarctica,...
The broadband albedo values retrieved from satellite sensors are usually compared directly to ground measurements. Some authors have noted the necessity of high spatial resolution estimates fill gap between measurements and retrievals. In this respect, hyperspectral airborne data with is a powerful tool. Here, new operational method for calculation apparent over spectral range 350–2500 nm presented. This uses Hemispherical Directional Reflectance Factor (HDRF) as proxy narrowband albedo,...
Abstract Soil organic matter is seriously affected by fires and suffers changes in stock, composition, distribution. In the North‐West side of Cantabrian Range (northern Spain) are very common. order to develop a cartographic technique map areas with high carbon stocks caused fire, we test based on calibrated VIS‐NIR soil models hyperspectral images. Total (TOC) oxidizable (OC) were measured 89 samples. The samples scanned spectrometer (400–2,500 nm), spectra resampled image channels....
The work described in this paper is aimed at validating hyperspectral airborne reflectance data collected during the Regional Experiments For Land-atmosphere EXchanges (REFLEX) campaign. Ground measured a vineyard were compared with data. A sampling strategy and subsequent ground processing had to be devised so as capture representative spectral sample of complex crop. linear model between was tried statistically tested. Results reveal sound correspondence (R2 > 0.97), atmospheric correction latter.
