+# CLOSP
+
+CLOSP (Contrastive Language Optical SAR Pretraining) is a multimodal architecture designed for text-to-image retrieval. 
+It creates a unified embedding space for text, Sentinel-2 (MSI), and Sentinel-1 (SAR) data.
+
+This repository contains all the separate visual encoders in PyTorch format.
+
+## Model Details
+The model uses three separate encoders: one for text, one for Sentinel-1 (SAR) data, and one for Sentinel-2 (MSI) data. 
+During training, it uses a contrastive objective to align the textual embeddings with the corresponding visual embeddings (either SAR or MSI).
