NASA's MODIS/Terra satellite provides an 8-day composite of land surface temperature and emissivity at a 1-kilometer resolution globally. The dataset includes daytime and nighttime temperature bands, quality assessments, observation times, view angles, and clear-sky coverage. It is produced by the National Aeronautics and Space Administration and is available as Version 6.1.
A case–control study of 242 individuals (174 with T2D, 68 controls) conducted by Shusi Ding, last updated in June 2026. It contains targeted LC–MS/MS quantification data for 19 plasma N-acetyl amino acids (NAcAAs). The data was used to develop an 8-metabolite diagnostic panel for T2D discrimination.
A study by Jiani Chen analyzed plasma samples from 106 rheumatoid arthritis patients and 10 healthy controls using liquid chromatography–mass spectrometry. The analysis tentatively annotated 2,279 metabolites and 2,987 lipids, identifying 12 core features associated with treatment non-response. Machine learning models using these features achieved area under the curve values exceeding 0.90 in internal cross-validation.
Plasma metabolomic and lipidomic data from 106 rheumatoid arthritis patients and 10 healthy controls, collected by Jiani Chen and last updated in 2026. Liquid chromatography–mass spectrometry analysis tentatively annotated 2,279 metabolites and 2,987 lipids, with 12 core features identified as potential biomarkers for treatment non-response. Machine learning models using these features achieved preliminary area under the curve values exceeding 0.90 in internal cross-validation.
A protocol document for a randomized controlled trial comparing wearable low-level laser therapy to manual acupuncture for chronic insomnia. The study, authored by Yuchuan Shen and last updated in June 2026, plans to enroll 106 adults and measure outcomes using standardized scales like the Insomnia Severity Index and Pittsburgh Sleep Quality Index. It is registered with the identifier ITMCTR2025000977.
A 2026 clinical trial protocol document authored by Yuchuan Shen details a study comparing wearable low-level laser therapy (laser acupuncture) to manual acupuncture for treating chronic insomnia. The protocol describes a single-center, assessor-blinded, superiority randomized controlled trial involving 106 adults. It outlines the study design, intervention details, primary and secondary outcome measures, and analysis plan.
Global satellite data from the AIRS instrument on NASA's Aqua spacecraft provides near real-time, calibrated infrared radiance measurements. This dataset is a 324-channel subset of the AIRIBRAD_NRT_005 product, converted to the BUFR format and includes AMSU footprints to meet a three-hour latency requirement. It is intended for time-sensitive applications but contains a documented spectral shift for channels in the L1b v5 product following a 2021 spacecraft maneuver.
NASA's CAM5K30CFCLIM product provides Principal Components Analysis (PCA) coefficients used to generate high spectral resolution land surface emissivity. This monthly climatology is derived from a weighted average of ASTER and MODIS satellite data spanning 2003 through 2021. The dataset includes variables for PCA coefficients, sample weights, laboratory version numbers, and geospatial coordinates at a 0.05-degree resolution.
Eight-day composite global data layers for evapotranspiration (ET), latent heat flux (LE), and their potential counterparts, produced at a 500-meter pixel resolution. The dataset is generated by NASA using the MODIS sensor on the Terra satellite and an algorithm based on the Penman-Monteith equation, incorporating meteorological reanalysis and MODIS land products. Its availability on multiple major data platforms indicates established use and reliability.
A retrospective clinical study of 453 children with Langerhans cell histiocytosis (LCH) treated at a single hospital in Egypt between 2007 and 2021. The dataset, authored by Seham Hassan and shared under a CC-BY-4.0 license, focuses on 80 patients with hepatic involvement to identify structural and functional prognostic indicators. It includes data on liver function, hepatomegaly Z-scores, treatment response, and survival outcomes.
Eighty pediatric patients with liver involvement from a cohort of 453 children with Langerhans cell histiocytosis (LCH) were studied between 2007 and 2021. The dataset, authored by Seham Hassan and shared under CC-BY-4.0, analyzes structural and functional liver factors to identify prognostic determinants. Hepatic dysfunction was associated with a 5-year overall survival of 39.4%, compared to 92.6% for patients with preserved liver function.
A 2026 multicenter cross-sectional study of 423 treatment-naïve chronic hepatitis B patients aged ≤30 years with persistently normal ALT who underwent liver biopsy. The research, authored by Pei-pei Wang, developed and validated the Y-HAL model to predict significant histological injury, finding such injury in approximately 48% of the cohort.
TRMM_2A55UW is a Level 2 product from the Tropical Rainfall Measuring Mission Ground Validation effort, providing a 3D cartesian grid of radar reflectivity and velocity. It is generated only for volumes of interest, defined as those within +/-15 minutes of satellite overpass times or with significant rainfall. The data supports validation of satellite precipitation estimates against ground-based measurements from primary sites in Darwin, Houston, Kwajalein, and Melbourne.
Data and code supporting a 2021 Cryosphere Journal paper on a novel diffuse reflectance probe. The dataset includes vertical profiles of temperature, salinity, and spatially resolved diffuse reflectance from two Arctic sampling sites, alongside Monte Carlo simulation results and validation data from microsphere solutions. Christophe Perron from the Centre National de la Recherche Scientifique authored the work.
Imagery and acoustics collected during the RV Investigator voyage IN2024_V02 between March 31 and April 19, 2024. The Marine National Facility Deep Towed camera captured video and stereo stills to monitor basketwork eels (Diastobranchus capensis) on Patience seamount. This data contributes to a CSIRO project on monitoring Key Natural Values in marine parks using acoustic and optical methods.
39 FIFE ground measurement sites provide instrument-corrected spectral radiances across eight bands, extracted from NS001-TMS imagery. The data set contains a small number of observation dates per site, with multiple viewing angles from flight grid patterns. It includes geographic location, viewing, and solar angles for each observation, with radiances corrected using atmospheric aerosol optical thickness and gaseous absorption profiles.
Top-of-the-canopy broadband albedo and radiation fluxes were measured at two flux tower sites in southern Africa from March 2000 through December 2002. The dataset includes shortwave, near-infrared, and longwave radiation measurements from towers in the Kataba Local Forest near Mongu, Zambia, and Kruger National Park, South Africa. Mean values are provided at 15-minute intervals for Mongu and 30-minute intervals for Skukuza.
102 pairs of human HCC and adjacent normal tissues were analyzed via immunohistochemistry for JCAD protein expression. The dataset, authored by Zhonghua Wang and last updated in May 2026, integrates bioinformatics analysis from TCGA, GEO, and GTEx with clinical validation. Elevated JCAD expression was significantly associated with portal vein tumor thrombosis and reduced disease-free survival.
A dataset of 1,197 radiomics features extracted from diffusion MRI maps for 232 patients with liver tumors. The data was used to construct logistic regression models for differentiating hepatocellular carcinoma from hepatic hemangioma. The dataset was created by Jingwen Yu and last updated in May 2026.
