Direct Assimilation of Satellite Visible and Near‐Infrared Radiances to Improve Aerosol Simulations

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 9, September 2026.
Abstract Existing satellite‐based aerosol data assimilation approaches mostly rely on assimilating retrieved aerosol products, which suffer from inconsistencies between retrieval assumptions and model representations, as well as uncertainties in the retrieved aerosol parameters.

Methane Emissions From Wildfires: Trends and Anomalies

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.
Abstract Wildfires emit smoke particles and trace gases including greenhouse gases into the atmosphere, impacting the environment and leading to detrimental impacts on human health and economy. The estimation of spatially and temporally resolved methane emissions from biomass burning (BB) provides critical information in developing measurement‐informed

A Novel Ice Cloud Optical Property Model for Passive and Active Remote Sensing Applications

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract A new broad‐spectrum ice cloud optical property model, namely the Passive‐Active Remote Sensing Consistent (PARSC) model, is developed to achieve consistency between passive and active sensor‐based ocean‐occurring ice cloud property retrievals.

Spectral‐Resolved Light at Night: TEMPO Observations and Background Correction

Earth and Space Science, Volume 13, Issue 6, June 2026.
Abstract Artificial Light at Night (ALAN) poses risks to public health and ecosystems. While long‐term remote sensing has tracked global nighttime light, spectrally resolved light at night (spectral light at night (SLAN)) data from geostationary orbit only became available with NASA's Tropospheric Emissions: Monitoring of Pollution (TEMPO) mission. Its

Anomalous Opaque Clouds Revealed by Collocated MODIS and CALIOP Retrievals

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract This paper examines discrepancies between cloud optical thickness (COT) retrievals from the Moderate Resolution Imaging Spectroradiometer (MODIS) cloud product, and cloud opacity measurements from the Cloud‐Aerosol Lidar with Orthogonal Polarization (CALIOP) lidar.

Fluorescence Quantum Efficiency Data for Europe 2018–2025

Geoscience Data Journal, Volume 13, Issue 2, April 2026.
We present a new dataset of fluorescence quantum efficiency (ΦF) across Europe and northern Africa (2018–2025). Derived from TROPOMI SIF and MODIS PAR at 0.05° resolution, the dataset provides daily, decadal and monthly coverage. The dataset includes input bands and quality layers, enabling applications in vegetation stress monitoring and drought ...

35 OECD Ülkesinde Vergi İdaresinin Etkinliği: VZA Yöntemi

Sosyoekonomi
Vergi idarelerinin etkinliği gerek vergi maliyetleri gerekse vergi gelirleri bakımından analiz edilmelidir. Vergi maliyeti düşüklüğü mükellefin gönüllü uyumunu artırmak suretiyle vergi kayıplarını azaltır ve toplam kamu geliri miktarını artırır. Üstelik hızlı ve doğru vergilendirme, vergileme sürecini kısalttığından Tanzi etkisinin ortaya çıkma riskini
